摘要: A pulsed laser is provided wherein the B-integral accumulated in pulse reduced using a semiconductor wafer. generated by source. The passes through wafer that has negative nonlinear index of refraction. Thus, accumulates B-integral. then fed into amplification medium, which positive may make plurality medium and accumulate during non-linear phase change. wavelength are chosen such substantially cancels medium. There be additional accumulation if optical mediums as lens or glass plates. effects self-phase modulation reduced.
