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.
