【摘要】 <正>连续染料激光器因其波长连续可调,在激光光谱、激光化学以及激光同位素分离等获得了广泛的应用.但因染料喷流的不稳以及受外界振动、温度、市电等影响,频率稳定度较差.例如S-P380A环形染料激光器及国内同类产品,取样时间小于1秒的峰峰频率波动约为20MHz,1秒至3秒时为40MHz,取样时间再长漂移更大.为提高其频率稳定性、压缩其线宽以满足高分辨激光光谱的要求,可把它锁频于一稳定的外部参考腔.更多还原

【Abstract】 The frequency stabilization of dye laser is described. The laser frequency is stabilized to the side of a transmision curve of an optical cavity by means of the usual differential servo technique. With a PZT cavity mirror driven by fast servo electronics and a galvoplate driven by slow servo electronics, the linewidth of the jet stream dye laser is reduced to 1 MHz. Experimental result is presented on the measurement of saturation spectroseopy of sodium D1 line.更多还原
