A power control method for a laser system comprising laser diodes arranged in diode banks is provided. Each diode bank comprises at least one of the laser diodes and has a maximum power. The method comprises operating a first diode bank of the diode banks to output a first power; and concurrently operating other of the diode banks to output other powers, at least one of the other powers being different than the first power.

Laser system and method of tuning the output power of the laser system

A semiconductor laser oscillator includes a diode unit configured from a plurality of banks, in which one bank is configured from a plurality of laser diodes connected in series. The diode unit includes a wavelength locking mechanism for locking to a plurality of wavelengths. The semiconductor laser oscillator includes a controller 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 as a whole to a required output.
