Abstract :
Summary form only given. We report the cancellation of B-integral accumulated in a regenerative amplifier by using a GaAs plate that has negative nonlinear index of refraction at 1.053 /spl mu/m. The nonlinear index of refraction is about three orders of magnitude larger than Nd:glass or KDP so a thickness of less than 1 mm is required. We show the compressed pulse duration measured as a function of accumulated B-integral increases without the compensator plate as B exceeds 1, while with the GaAs plate installed, the pulse duration remains fixed. 1.053-/spl mu/m chirped pulses are generated in a Nd:LiYF/sub 4/ laser oscillator coupled into a 0.8-km single-mode fiber. They are subsequently expanded in a grating pair.
