Repetition Rate Amplified Ti:Sapphire Laser
Beacon
Up-Conversion Spectrometer
Hatteras
Transient Absorption Spectrometer
Femtosecond Harmonics Generator
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.
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.
Femtosecond Optically Gated Fluorescence
Kinetic Measurement System FOG100
<100 fs temporal resolution available
Sum
frequency generation (up-conversion) method is used in the FOG100 femtosecond optically
gated (FOG) fluorescence kinetic measurement system to achieve a temporal resolution
better than 100 femtoseconds. The FOG100 is a first commercially available complete system
for femtosecond lifetime and kinetic spectroscopy measurements. The system has been designed to be matched with any type of femtosecond laser operating at
> 1 kHz pulse repetition rate.
The system includes optical and mechanical components installed on a breadboard; monochromator; selected photon counting PMT; electronic unit; PC software, installation and test measurements. The electronic unit contains photon counter, step motor driver, computer controlled PMT power supply and low voltage power supplies.

Listen
what our customers tell:
"We have bought main component of our femtosecond
laser system TISSA 50 a couple of years ago and quite happy with
it. TISSA50 fs generator is pumped by Coherent Ar laser, Innova 316P. This combination
works fine, we have ~60 fs pulses without compressor and the whole system is in working
condition after one hour of warming up.
Next is up-conversion system, FOG100. I was impressed by the way it was installed. Two
fellows came, assembled generator and up-conversion in 4 days and in 5th day I have got
fluorescence decay of my sample together with answer I was trying to obtain using other
techniques during one year. Certainly, it’s excellent instrument.
