Abstract
In a laser diode module, a laser diode chip is disposed in a module casing. A heater heats the laser diode chip such that at least a temperature of the laser diode chip is kept constant. A temperature detector detects a temperature of the laser diode module. A temperature controller controls a calorific value of the heater in accordance with the detected temperature of the laser diode module. The temperature controller keeps the temperature of the laser diode module at a temperature higher than an operative temperature of a laser diode device incorporating the laser diode module.
