ABSTRACT:
A semiconductor laser device in which a thermosensitive element exhibiting a resistance variation with temperature is installed at a location more faithfully transmitting the temperature of a semiconductor laser element and the thermosensitive element is connected to a circuit for taking out the output from a photodetector receiving the light from the laser element so that, when a wavelength fluctuation is caused by a temperature variation, information is fed back so that a required quantity of light corresponding to that wavelength is obtained, whereby an optimal quantity of light may always be maintained, and an image recording apparatus using the same.
