Customer Inquiry:
I'm looking to purchase a SHG crystal for an Nd YLF laser with the following
specs
Pulse rep rate: 10Hz
Pulse width: ~20-30ns
Wavelength: 1053mm
Power: 400 - 700 mJ
Beam diameter: 7mm
Our current crystal is mounted on a heat sink which is temperature controlled so
if possible, could you indicate if you are able to help us mount the new crystal
on our existing heat sink?
Del Mar Photonics reply:
Ok please go ahead and begin production so as to avoid any further delay.
Pls try your best to help us by completing the crystal in 3 weeks. We will be
grateful for your assistance.
We will be placing our order by credit card. I believe Alexandra from your
company has our billing details.
I also await your reply on the the recommendation for glue if possible.
I quoted you that LBO crystal on July 13 - practically two weeks ago! We have
not such LBO in stock and production of the crystal will take some time - this
is normal situation and you should understand it. We will try to do our best in
case of getting order.
I also quoted BBO crystal from stock so if you are in a hurry you can order this
one.
As mentioned earlier, we are on a v tight schedule and we really need the
crystal within 2 weeks, latest 3 weeks and if that is not possible, we may have
to look elsewhere. I will try to see what i can do. But 3 weeks is really a
little too long. Do you think you can find a way to expedite production without
compromising quality?
thanks for the follow up. Very good, we are ready to start production right away
just to save a time! According to production technology it's absolutely
impossible to produce such big crystal within 3 weeks but we will try to do it
within 4 weeks. High quality of the crystal is very important for us! I think
for you too!
When do you expect to send us PO? Will it be a credit card order or standard PO?
> (i) As earlier mentioned, we currently maintain our crystal at 70deg C by
mounting it on a heat sink. Since we will have to mount the new crystal on the
heat sink ourselves, are you able to provide us with any glue that you think
might be suitable for our application? Of course, if the new crystal is not v
sensitive to temperature changes or needs to be maintained at some other temp,
pls make a recommendation accordingly
I'll check it with our experts and let you know shortly.
> (ii) Could you pls indicate the input face of the crystal and the polarization
direction so that it'll save us the trouble from checking?
Yes, will do!
> iii) Can you also include a 1" mount for our convenience in the event that we
do not need to temperature control the crystal?
Sure, no problem. We will send you our standard 1 inch diameter mount.
I'm pleased to let you know that we are willing to purchase the following LBO
crystal that you have quoted:
LBO, type I
theta=90, phi=12.2 deg
10x10x10mm
AR-1053/526.5nm
Price (FOB San Diego, CA): $2770
However we are ONLY agreeable if you can expedite production to 3 weeks or less.
We will make a decision on whether to polish and recoat our present crystal in
due course.
Also, we hope you can help us with the following:
(i) As earlier mentioned, we currently maintain our crystal at 70deg C by

Hi Alex,
We've been shopping around for our crystals and a lot of the other companies
have quoted us BBO crystals.
Does Delmar carry BBO crystals too? Are you able to give me an estimate for a
BBO crystal as well? I presume that the reason you recommended an LBO crystal
was because it has a better conversion efficiency compared with BBO?
Also, if we decide not to buy a crystal but instead just attempt to polish and
recoat our old crystal, would you guys be agreeable to doing it?
Pls pardon me for being blunt.
Thanks,
Tat

Hi Tat,
to answer your questions
> (i) Our current crystal is a type I BBO crystal. Since you have recommended an
LBO crystal, how do LBO and BBO crystals compare in general? What temperature
should it be maintained at?
LBO, with wide acceptance angle and small walk-off, type I and type II
non-critical phase matching (NCPM) in a wide wavelength range;
BBO, Because of a small acceptance angle and large walk-off, good laser beam
quality (small divergence, good mode condition,etc.) is the key for BBO to
obtain high conversion efficiency.
> (ii) What is the expected conversion efficiency of the crystal that you have
quoted? A rough estimate. For your reference, our old crystal was able to
achieve more than 50% conversion efficiency at max power (700mJ) with
temperature control.
SHG conversion efficiencies of more than 70% for pulse and 30% for cw Nd:YAG
lasers, and THG conversion efficiency over 60% for pulse Nd:YAG laser have been
observed by using Del Mar Photonics LBO crystal.
We will try to produce the crystal ASAP so we are ready to start production
right away just to save a time!
Please inform.
Thanks,
Alex

Thanks. I'll let you know our decision by next week but it would be really
helpful if you could speed up production to 2 weeks as we need the crystals
urgently.
Could you advise on the following too?

Hi Tat,
From your picture, there is no holder for the crystal, only on surface stick to
the heat sink. I am afraid the BBO crystal would separate from the heat sink
during the shipment so we suggest you mount it yourself.
> (iv) We need the new crystal urgently. Is there anyway to speed up the lead
time to around 2 weeks or so?
We will try to accelerate production - 3 weeks (some of our polishers are on
vacations during summer period).
> (iii) Are you able to do polishing of crystals? Our old crystal has a bad spot
on it (probably just the coating), so if you could also remove and polish the
old crystal and return it to us together with the new one, that would be
perfect.
We can help you, you can ship it to us, we will retest it and then give you a
confirmation if it is possible to repolish or not.
Do you need recoating?
We will charge $750 for repolishing and recoating. It will take ~ 3 weeks.

Hi Alex,
I've attached another picture of the crystal mounted on the heat sink which
should make things much clearer. This is the part that we will send to you if
you are agreeable to assisting us with the mounting.
The existing crystal is nominally 10mm by 10mm by 5mm (thickness). It sits on a
heat sink which is 24mm by 22mm.
Some questions I have
(i) Our current crystal is a type I BBO crystal. How do LBO and BBO crystals
compare in general?
(ii) What is the expected conversion efficiency of the crystal that you have

Pismo pulse picker The Pismo pulse picker systems is as a pulse gating system that lets single pulses or group of subsequent pulses from a femtosecond or picosecond pulse train pass through the system, and stops other radiation. The system is perfectly suitable for most commercial femtosecond oscillators and amplifiers. The system can pick either single pulses, shoot bursts (patterns of single pulses) or pick group of subsequent pulses (wider square-shaped HV pulse modification). HV pulse duration (i.e. gate open time) is 10 ns in the default Pismo 8/1 model, but can be customized from 3 to 1250 ns upon request or made variable. The frequency of the picked pulses starts with single shot to 1 kHz for the basic model, and goes up to 100 kHz for the most advanced one. The Pockels cell is supplied with a control unit that is capable of synching to the optical pulse train via a built-in photodetector unit, while electric trigger signal is also accepted. Two additional delay channels are available for synching of other equipment to the pulse picker operation. Moreover, USB connectivity and LabView-compatible drivers save a great deal of your time on storing and recalling presets, and setting up some automated experimental setups. One control unit is capable of driving of up to 3 Pockels cells, and this comes handy in complex setups or contrast-improving schemes. The system can also be modified to supply two HV pulses to one Pockels cell unit, making it a 2-channel pulse picker system. This may be essential for injection/ejection purposes when building a regenerative or multipass amplifier system. |

Hatteras-D
femtosecond transient absorption data acquisition system Future nanostructures and biological nanosystems will take advantage not only of the small dimensions of the objects but of the specific way of interaction between nano-objects. The interactions of building blocks within these nanosystems will be studied and optimized on the femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar Photonics, Inc. Thus we put a lot of our efforts and resources into the development of new Ultrafast Dynamics Tools such as our Femtosecond Transient Absorption Measurements system Hatteras. Whether you want to create a new photovoltaic system that will efficiently convert photon energy in charge separation, or build a molecular complex that will dump photon energy into local heat to kill cancer cells, or create a new fluorescent probe for FRET microscopy, understanding of internal dynamics on femtosecond time scale is utterly important and requires advanced measurement techniques.

Wavefront Sensors: ShaH Family A family of ShaH wavefront sensors represents recent progress of Del Mar Photonics in Shack-Hartmann-based technology. The performance of Shack-Hartmann sensors greatly depends on the quality of the lenslet arrays used. Del Mar Photonics. developed a proprietary process of lenslet manufacturing, ensuring excellent quality of refractive lenslet arrays. The arrays can be AR coated on both sides without interfering with the micro-lens surface accuracy. Another advantage of the ShaH wavefront sensors is a highly optimized processing code. This makes possible real-time processing of the sensor data at the rate exceeding 1000 frames per second with a common PC. Due to utilizing low-level programming of the video GPU, it is possible to output the wavefront data with a resolution up to 512x512 pixels at a 500+ Hz frame rate. This mode is favorable for controlling modern LCOS wavefront correctors. The family of ShaH wavefront sensors includes several prototype models, starting from low-cost ShaH-0620 suitable for teaching laboratory to a high-end high-speed model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD sensor with cooling down to -100°C. This makes it possible to apply such a wavefront sensor in astronomy, remote sensing, etc. |

Frequency-stabilized CW single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong Kong. DYE-SF-077 features exceptionally narrow generation line width, which amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation line width of commercial lasers. Prior to this model, the narrowest line-width of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an acousto-optical modulator, which, as a rule, complicates the design and introduces additional losses. A specially designed ultra-fast PZT is used for efficient suppression of radiation frequency fluctuations in a broad frequency range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules, Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution spectroscopy |
