Abstract: A single longitudinal mode diode laser module including a laser diode (1) and an external resonator using a volume holographic grating (3) having a prescribed reflective bandwidth is made amenable to automatic power control by controlling the temperature of the laser diode such that the laser power may be allowed to increase monotonically with an increase in the input current. Therefore, the output laser power can be controlled at a constant level by automatic power control or by adjusting the input current while monitoring the laser power at any desired level of the laser power.
