The preliminary result of the frequency stabilization of an InGaAsP semiconductor laser using the optogalvanic effect of a gas absorption cell is reported. The optogalvanic signal of the discharge absorption cell is used as a frequency standard.

• 采用光吸收作用使放电气体吸收池电流改变，即“光电压”信号作为频率标准，对InGaAsP长波长半导体激光器进行稳频。
