Teahupoo Rider and other options for Amplified Ti:Sapphire Laser

1. We offer integrated oscillator/amplifier system Teahupoo Rider. Teahupoo Rider is a fully-integrated all-in-one-box system that includes Trestles Finesse oscillator or Buccaneer SHG diode-pumped fiber oscillator, pulse stretcher, regenerative amplifier pumped by multi kHz Nd:YAG pump laser and pulse compressor. Teahupoo Rider has a factory preinstalled repetition rate of 2, 5 or 10kHz and ideal for low cost femtosecond micromachining systems, OPA pumping, ultrafast spectroscopy and variety of applications in life sciences.

One-box system Trestles Finesse that include Trestles mini Ti:Sapphire oscillator and built in DPSS pump laser

When choosing specific Trestles Finesse model please indicate required CW pump power (4W or 6W), Ti:Sapphire pulse duration and required tuning range (or tuning range, where you want to achieve maximum performance)

Tuning range can be customized at the factory by choosing one of standard or custom made optics set. Typical tuning curves for 4W CW pump laser for two standard optics sets are shown in the Trestles Finesse brochure. For example, with 4W CW pump laser and long-wave mirrors set tuning range can be extended up to 940nm. With 6W CW pump laser tuning range can be extended up to 980nm.

2. If you already have a Ti:Sapphire oscillator, we can offer you stand alone Ti:Sapphire amplifier. Two standard models are available: Wedge M multipass or Wedge R regenerative.

Ti:Sapphire oscillator and multipass amplifier

Each amplifier is customized to the customer's amplifier pump laser.

2. Custom Teahupoo Rider systems with a pump laser of your choice are also available. Depending on the required specifications we can recommend a pump laser and make required adjustments for optimum performance.
The following specifications can be achieved:
Repetition rate: single pulses, 10 Hz up to 10kHz
Pulse duration: 100fs, 50fs, 30fs, <30fs
Pulse energy: from 100 mJ per pulse to few mJ per pulse
Tunability: both fixed wavelength and tunable options are available - please indicate required tuning range.
