Abstract
A direct diode laser oscillator includes plurality of LDs that emit laser beams of multiple wavelengths, respectively, a fiber array formed by binding emitting ends of a plurality of feeding fibers that respectively transmit the laser beams of multiple wavelengths emitted from the plurality of LDs, a spectral beam combining unit that spectral-beam-combines the laser beams of multiple wavelengths emitted from the fiber array, a reflected light detecting fiber that is arranged adjacent to the fiber array and receives, through the spectral beam combining unit, reflected light of the laser beams of multiple wavelengths reflected by a work material, and a photodetector that detects the reflected light emanating from the reflected light detecting fiber.
