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 1):
A method for producing single-frequency operation of a laser beam generated by a laser beam system, comprising:\n providing a laser for emitting a laser beam within a laser beam cavity, the cavity having a length, wherein the length of the cavity may be adjusted to one of a plurality of cavity lengths; emitting the laser beam at each one of the plurality of cavity lengths; providing a detector, operably coupled to a computer, for:\n receiving at least a portion of the laser beam emitted at each one of the plurality of cavity lengths; and \n detecting the presence of transverse modes, longitudinal modes, or both, in the received laser beam emitted at each one of the plurality of cavity lengths and when at least transverse modes, longitudinal modes, or both, are detected, generating at least one laser beam signal having a beat-note indicative thereof; \n selecting, based upon the generated at least one laser beam signals, at least one cavity lengths for eliminating the beat-note and producing single-frequency operation of the laser beam; and adjusting the length of the cavity one of the one or more selected cavity lengths.
