Patent ID: 7777940

Claim:
An optical system for chirped pulse amplification and phase dispersion comprising: a active dispersion controller for receiving an input optical pulse from a mode locked laser and controlling a third and fourth order dispersion property of the input optical pulse to produce an optical output pulses; a stretching re-circulating loop serially connected to the active dispersion controller for stretching the optical output pulses in time; an optical amplifier serially connected to the stretching circuit for amplifying the stretched optical output pulses; a compressing re-circulating loop serially connected to the output of the optical amplifier for compressing the amplified stretched optical output pulse to produce a compressed optical output pulse; and a feedback loop connected between an output of the compression re-circulating loop and the active dispersion controller for feeding a feedback optical signal to the active dispersion controller for adjusting the third and fourth order dispersive property of the active dispersion controller to actively fine tune the optical output pulses.
