英文摘要	A stabilized laser device has a semiconductor laser, an optical detector for performing photoelectrical conversion of laser light from the laser and producing a detection signal, and a variable voltage power source for outputting an analog voltage signal as a preset value for the laser output light. A differential amplifier produces a differential signal representing the difference between the detection signal and the preset analog voltage signal, and a gate circuit supplies a clock pulse from a clock pulse generator to one of the up and down terminals of an up/down counter in accordance with the output signal from the differential amplifier. A D/A converter converts the output digital signal from the counter to an analog signal and supplies it to a driver circuit for the laser. The D/A converter generates an analog signal which corresponds to the product of the output digital signal from the counter and the preset analog voltage signal from the variable voltage power source.
