英文摘要	in the high-power laser facility, frequency modulation to amplitude modulation (fm-to-am) effects has seriously affected the power balance between beams and restricted the laser flux levels of safe operation in the system. for fm-to-am effects produced by gain-narrowing effects, according to the amplifier gain-narrowing function model, after simulating and analyzing the properties of fm-to-am effects, a corresponding compensation function is designed. using sinusoidal compensation function, with the use of a birefringent crystal and liquid crystal modulator, adjusting the crystal angle in the range of 45 degrees, the center wavelength could be reduced in the magnitude of the range from 0 to 30dbm. by changing the voltage of the liquid crystal, the center wavelength could be adjusted within 1051.5-1054.5nm freely. for the regenerative amplifier with the gain of 70db and input center wavelength of 1053nm and bandwidth of 0.7nm, the output fm-to-am magnitude could be controlled within similar to 11% by this compensation system.
