Abstract

The highest power is achieved in a laser system by extracting all the stored energy in pulses of duration limited by the gain bandwidth of the laser medium. A chirped pulse amplification (CPA) technique is necessary for efficient amplification of the shortest pulses (approxintately 100 fs) in KrP large aperture amplifiers in order to overcome the power limit imposed by nonlinear effects such as two-photon absorption, self-focusing, self-phase modulation, and Raman generation, In the SPRITE KrF laser, it is necessary for 100 fs input pulses to be stretched to approximately 10 ps to allow amplification to several times the saturation fluence (Esat= 2 mJ/cm2).
