Frequency-stabilized CW single-frequency ring Dye laser, model DYE-SF-077, is a
further development of model DYE-SF-07. It now includes a system of frequency
stabilization on the basis of a thermo-stabilized interferometer and a fast
electronic driver.
Laser 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
570-700 nm, output > 1.5 W (10 W pump), linewidth < 100 kHz rms, frequency drift
< 30 MHz/hour, smooth scanning 6/20 GHz.
The DYE-SF-077 laser cavity has horizontal orientation, the optical mounts of
the cavity elements are attached to a rigid base plate, which is further
stabilized by a volumetric framework with three invar rods underneath.
Additional passive stability of the position of cavity elements is provided by
the vibration isolating design of the laser base.
Dye laser DYE-SF-077 is the first representative of the new generation of dye
lasers that offer to the user virtually the same level of convenience and
simplicity of operation as with a solid-state tunable laser. As a result we are
able to offer an option of combined configuration of DYE-SF-077 with Ti:Sapphire
laser.
Laser DYE-SF-077 may be equipped with a USB compatible interface to remotely
scan the generation line of the laser and to perform multi-channel data
acquisition. Laser DYE-SF-077 also may be shipped together with an atom cell and
a system for reduction of long-term generation line drift. Besides, laser
DYE-SF-077 in combination with highly-efficient resonant frequency doubler
FD-SF-07 delivers several hundreds milliwatts of narrow-band UV radiation within
the 285–350-nm range.

Actively frequency-stabilized, continuous-wave, single-frequency
ring Dye laser, model DYE-SF-077
Unique DYE-SF-077 laser has more narrow linewidth for Dye lasers on the present
market. DYE-SF-077 laser has super-narrow linewidth (< 70 kHz) and unique Auto
Re-lock function which is extremely useful in a work with frequency stabilized
laser.
General description
•Ring design, three wavelength selectors: birefringent filter, thin and thick
etalons, electronically controlled thick etalon to ensure laser operation in a
single longitudinal-cavity mode.
•Ultra-narrow line width up to < 70 kHz rms: active frequency stabilization to
an external reference cavity, special fast PZT actuator with extended response
bandwidth.
•Unique function Smart Auto-Relock that allows uninterrupted laser operation in
the frequency stabilization mode under arbitrary external perturbations.
•Smooth scanning capability: up to 20 GHz.
•Actively thermostated high-finesse reference cavity, frequency drift <40MHz/hr.
•External lock capability for stabilization to an absolute reference (e.g.
iodine saturated absorption line).
Wavelength range, power
•Spectral ranges 570-620 / 620-700 nm
•Output power at max gain 590 / 650 nm 1W or better with 6W pump (DPSS, 532 nm,
TEMoo).
•TEMoo mode, linear polarization.
Design
•Absolutely dry dye-jet laser: the laser has a reliable shutter for the dye
solution during powering up and switching off the circulation system.
•Most of the mounts are placed on a horizontal base plate, which is also the top
element of the compact rigid 3-D frame made from three invar rods that ensures
high stability of the optical element positions.
•Ease of adjustment, simplified laser alignment in the ring configuration
because of preliminary optimization of the elements in the linear cavity,
exceptionally accurate alignment of the pump beam position.
•Premium sapphire nozzle.
•Enclosed cavity with nitrogen purge port.
•Ergonomical and reliable electronic control unit featuring a built-in generator
for smooth scanning of the laser frequency.
Dye Circulation System
•Compact and powerful system of dye solution circulation with a leak-free
magnetically coupled pump.
•Efficient system for suppression of pressure fluctuations in the dye
circulation loop.
•The dye solution circulation system of DYE-SF-077 is designed to make the
procedure of dye change convenient and clean. Laser DYE-SF-077 may be shipped
with several circulation systems, in which case switching between working
spectral ranges will be extremely fast and simple.
