Document Type and Number:
Japanese Patent JP2023145805
Kind Code:
A
Abstract:
To provide an optical device which can inhibit adhesion of contaminants to an end surface of a semiconductor laser element.SOLUTION: An optical device 100 includes: a semiconductor laser element 110 which emits a laser beam; an optical component 130 which faces a light emission surface 111, from which the laser beam 210 is emitted, and is disposed spaced apart from the light emission surface 111; and a case 140 which houses the semiconductor laser element 110 and the optical component 130 and has an introduction port 141 for introducing a gas and an exhaust port 142 for exhausting the gas. The introduction port 141 and the exhaust port 142 are arranged so that the gas introduced from the introduction port 141 flows near the light emission surface 111 of the semiconductor laser element 110.SELECTED DRAWING: Figure 1A
