Femtosecond optical parametric oscillator Tsunami®

Ti:sapphire

The superior design of the Tsunami prism dispersion compensation enables short, transform-limited pulses. The unique λ-track prism movement enables excellent beam pointing as the laser is tuned. The use of slits for wavelength selection in femtosecond operation, combined with advanced dispersion compensation allows wide pulse duration adjustment over the femtosecond range from 900 femtoseconds. The Tsunami laser can then be easily converted to picosecond mode to cover from less than 2 picoseconds to greater than 100 picoseconds with use of the appropriate GTI. Flexibility The Tsunami series contains the flexibility to have both femtosecond and picosecond pulses on the same platform with the 3960 series, a femtosecond only version with the 3941, and picosecond only with the 3950 series. The Tsunami series can be pumped with a Millennia eV in powers of 5, 10 or 15 watts so that the laser output can match the required amount of energy for each experiment. Short Pulse Width The short pulse Tsunami systems use high-performance optics to allow >65 nm of bandwidth to produce 800 mW of average power with >350 kW of peak power. Expansion The Tsunami oscillator can be combined with Spectra-Physics harmonic generators and optical parametric oscillators, such as the Inspire™ OPO. Optional pulse picking can be added to adjust the repetition rate from single shot to 8 MHz, while still providing enough pulse energy for demanding fluorescence lifetime applications.
