FEMTIS Femtosecond Ti:Sapphire Laser

FEMTIS Ti:Sapphire Laser is high power, broadly tunable laser source for femtosecond phenomena investigation. It operates on the revolutionary principle Kerr Lens Modelocking.

Three-invar-bar vertical plane folded cavity is specifically designed to utilize changes in the spatial profile of the beam produced by self-focusing resulting from the optical Kerr effect in the Ti:Sapphire crystall.
FEMTIS Ti:Sapphire Laser delivers more than 400 mW of power in transform limited pulses of less than 100 fs with solid-state dependability and convenience.

FEMTIS Ti:Sapphire Laser allows easy switching between two separate optical cavities optimized for femtosecond and picosecond operation. The picosecond cavity is dispersion compensated via a Gires-Tournois (GT) interferometer designed to provide the much higher negative GVD required to yield pulses in 1-3 ps range (shown with dotted line in the schematic configuration).
