【摘要】 提出了一种利用半导体光放大器(SOA)环形腔和非线性光学环镜(NOLM)对锁模脉冲进行压缩的方案。数值计算的结果表明:对输入功率为 1 mW, 脉宽为 20 ps的锁模脉冲,脉冲压缩因子超过117,输出脉冲FWHM小于150 fs,峰值功率达到6 W且基本无基座。更多还原

【Abstract】 A designed method for the compression of mode-locked pulse train based on the semiconductor optical amplifier (SOA) ring cavity and nonlinear optical loop mirror (NOLM) is introduced. Numerical simulations show that, for incident mode-locked pulses with peak power of 1mW and pulse width of 20ps, the pulse compression factor can exceed 117, the FWHM of output pulse is less than 150fs, and the pulse is nearly free pedestal at peak power up to 6W.更多还原
