Abstract
An optical apparatus includes: an optical component opposed to and spaced apart from a light-emitting surface through which laser light is emitted; a case that houses a semiconductor laser element and the optical component and includes an introduction port for introducing gas and an exhaust port for exhausting the gas; and a flow passage section (i.e., a tubular body) including a spray port for spraying the semiconductor laser element with the gas introduced from the introduction port.

An optical apparatus, comprising:
- a semiconductor laser element that emits laser light;
- an optical component opposed to and spaced apart from a light-emitting surface through which the laser light is emitted;
- and
- a case that houses the semiconductor laser element and the optical component, and includes an introduction port for introducing gas and an exhaust port for exhausting the gas;
- wherein the introduction port and the exhaust port are arranged as to form a flow path through which the gas introduced from the introduction port is directed at the light emitting surface of the semiconductor laser element.
