Abstract
A control device for controlling a temperature of a laser device includes a pulse width modulation (PWM) signal generator, a temperature acquisition circuit, a voltage comparator, and a logic circuit. The a pulse width modulation (PWM) signal generator configured to generate a PWM signal; a temperature acquisition circuit configured to acquire a temperature of the laser device and convert the temperature into a measurement voltage; a voltage comparator configured to compare the acquired measurement voltage associated with the temperature of the laser device with a temperature threshold voltage and output a comparison result signal; and a logic circuit configured to generate a drive signal based on the PWM signal and the comparison result signal to drive the laser device.
