Schematics of CPA — chirped pulse amplification.
Correspondingly, the fiber laser and slab lasers are the technologies most suitable for achieving higher average power Fiber laser technology uses
laser pulses, higher repetition rate and higher wall-plug ef the principle of larger surfaceficiency. The main components of a fiber laser are shown in to-volume ratio.

4.2.5 CPA — chirped pulse amplification
Invented for lasers by G. Mourou and D. Strickland, chirped
pulse amplification (or CPA) is a process that stretches the
short pulse in time, amplifies the now-longer laser pulse and
then compresses the amplified pulse. This multi-step pro- CPA technique was origicess relieves the optical component of laser amplifiers from nally developed for radar,
