Abstract: Semiconductor laser apparatus wherein a semiconductor laser device and a temperature sensor for sensing the temperature of the laser device are mounted on a heat sink or base and airtightly encapsulated. In one embodiment the heat sink or base is mounted on temperature control apparatus which in turn is electrically controlled in response to the output from the temperature sensor. In another embodiment, a laser beam intensity sensor whose output varies over a wide range depending upon an environmental temperature is also temperature controlled so that the semiconductor laser apparatus may be controlled with a higher degree of accuracy.
