The effect of dispersion on FM-AM coversion in high power laser front end
色散对高能激光光纤前端FM-AM效应的影响

Sinusoidal phase modulated pulse could provide broad bandwidth and high modulation frequency for spectral dispersion method in high power laser driver system. Phase modulation could be converted to intensity modulation due to dispersion during the pulse propagation in the fiber,and the intensity modulation enhances the nonlinear effect in the large-mode-area double-clad fiber amplifier and make the spectral controlling more difficult. 2 GHz and 14.25 GHz phase modulation pulses propagated in fibers with dif...
