Beschreibung
Zusammenfassung:	A semiconductor laser oscillator (11) includes a diode unit (11u) configured from a plurality of banks, in which one bank is configured from a plurality of laser diodes connected in series. The diode unit (11u) includes a wavelength locking mechanism for locking to a plurality of wavelengths. The semiconductor laser oscillator (11) includes a controller (114) configured to control input currents to the laser diodes of each of the plurality of banks individually in correspondence to a characteristic of a wavelength locking efficiency, and to control an output of the diode unit (11u) as a whole to a required output.
