Abstract:
A method and system for obtaining single-frequency operation of a laser system. A laser beam is emitted from a laser cavity, having an adjustable length, at a plurality of cavity lengths. At least a portion of the laser beam is received at a detector, which detects the presence of transverse and/or longitudinal modes in the laser beam, and generates a laser beam signal having a beat-note indicative thereof. The laser beam signal for each of the plurality of cavity lengths can be analyzed, and a cavity length of best mode purity, indicating single-frequency operation, can be selected. The laser beam system can emit a laser and have a laser beam splitter for directing at least a portion of the emitted laser beam to a laser beam detector for generating at least one laser beam signal therefrom, and an actuator for adjusting the length of the laser cavity.

Claim (Index 9):
A laser beam system for producing single-frequency operation of a laser, the laser system comprising:\n a laser for emitting a laser beam, the laser beam emitted in a laser cavity having a first end and a second end, and having a length, the cavity comprising at least,\n a diffraction grating, positioned at the first end of the cavity, for providing a mirror within the cavity; \n an output coupler, positioned at the second end of the cavity, wherein the distance between the diffraction grating and the output coupler defines the length of the cavity, and \n a gain medium, positioned between the diffraction grating and the output coupler, \n a laser beam splitter for receiving and dividing the emitted laser beam and for directing at least a portion of the divided laser beam to a laser beam detector, a laser beam detector, for receiving and detecting the directed portion of the emitted laser beam from the laser beam splitter, and for generating at least one signal indicative thereof, an actuator, for actuating at least the diffraction grating, the output coupler, or both, to adjust the length of the cavity to produce a single-frequency operation of the laser.
