摘　　要：利用液晶盒作为电光调制器,提出和建立了一套激光功率稳定装置。此装置结构简单,重量轻,驱动电压低,经济实用。实验结果表明,它可将激光输出功率起伏由60%左右降到5%以下,并且此装置可作为线性很好的光衰减器。A stablizing laser power system has been installed with the characteristic of symple structure, low weight, low driving voltage and low cost. In this system a liquid-crystal cell is used as a power control device. Experimental results show that it can reduce the fluctuation of laser output from about 60% to 5%, and it can also be used as a linear laser attenuator with good performance.
