A frequency converting laser device includes a plurality of laser diodes each adapted to produce an output laser light beam and a plurality of optical fibers, each coupled to the output of a corresponding laser diode and including a built-in grating in the optical fiber arranged so as to provide a beam having a specific wavelength and to reflect a small portion of such beam back into the laser diode while transmitting the beam so that the laser diode will produce a beam of that wavelength. The device further includes frequency converting structure adapted to receive the transmitted beams of laser light and to change the frequency of each input beam to produce output beams at desired frequencies.
