Abstract
A semiconductor laser oscillator includes laser diode modules. A temperature sensor directly or indirectly detects a temperature of at least one of the laser diode modules. A collimating lens collimates respective lasers emitted from the laser diode modules. A grating performs spectrum beam coupling for the lasers emitted from the collimating lens. An incident angle varying mechanism changes incident angles of the respective lasers, at which the lasers emitted from the collimating lens are incident onto the grating in response to the temperature detected by the temperature sensor.
