Numerical simulation of ultrashort pulse amplification

Ultrashort pulses with high average power are required for a variety of technical and medical applications. To increase the power of ultrashort lasers, single, multi-pass, and regenerative amplifiers are used. Typical laser crystals for such amplifiers include the Ti:Sapphire or Yb:YAG laser crystals. We present a technique to model and simulate the amplification of ultrashort pulses of such laser systems. This technique allows to model both gain narrowing effects and decrease of beam quality caused by amplification of the laser beam. Detailed simulation results are presented.
