摘要： The invention features a frequency stabilized laser system including a laser source, a first detector, a second detectors, and a circuit. The laser source has an adjustable cavity length and, during operation, produces a control beam including two frequency components having different polarizations. The first detector absorbs a portion of the control beam, reflects the remaining portion of the control beam, and generates a first signal proportional to the intensity of the absorbed portion of the control beam. The second detector absorbs a portion of the reflected beam and generates a second signal proportional to the intensity of the absorbed portion of the reflected beam. The circuit receives the first and second signals from the detectors and generates a control signal based on the first and second signals that controls the adjustable cavity length of the laser source. The frequency stabilized laser system can be used in interferometry applications or any other application in which frequency stability is beneficial.

摘要： In a harmonically mode-locked laser, first (33) and second (34) optical beams are derived from the laser optical path which are directed, respectively, through first and second optical filters (37) having optical pass-bands (40, 41) that are displaced in frequency but which intersect at approximately the center frequency (f.sub.c) of operation of the laser. The free spectral range of a Fabry-Perot optical resonator (24) in the laser ring is deviated from a frequency exactly equal to the pulse repetition rate of the laser by a frequency (df) sufficient to permit changes in the length of the optical path to be manifested as changes in the wavelength of light transmitted along the optical path. Apparatus (39, 40, 42) for detecting the difference of intensity of light passing through the first and second filters can then be used to generate a signal proportional to the difference of intensity of such light for the purpose of adjusting, by length adjusting apparatus (43), the length of the optical path to compensate for spurious temperature-induced length variations.

摘要： A rod made of an insulating material having a thermal coefficient of expansion in the range from +1 to -1 part in 107 per degree centigrade is mounted between a pair of mirrors and hermetically sealed either within a glass or a stainless steel enclosure containing a gas discharge medium. The stainless steel enclosure may be clamped to and fixedly spaced from the rod by projections formed on the enclosure and symmetrically disposed around the rod toward the ends of the rod. The mirrors and an annular piezoelectric disc positioned within the enclosure between one of the mirrors and one end of the rod are axially mechanically biased against the ends of the rod either by a spring loading structure or by a gas pressure differential. An anode and an annular cathode electrically insulated from one another for operation at different potentials are mounted toward the opposite ends of the rod. A discharge path communicating with the gas discharge medium and including a portion of a bore axially extending through the rod is provided in the rod between and in communication with the anode and the cathode to provide a gas discharge for excitation of the gas discharge medium to produce a laser beam. This discharge path may be placed in a magnetic field having a component in the direction of the laser beam to Zeeman split the atomic transition line at which the laser action occurs so that the laser oscillates at two different frequencies and thereby produces an output beam with two components of different frequency and polarization. In response to a portion of the laser beam a feedback control circuit changes the thickness of the piezoelectric disc to maintain the spacing between the mirrors as required, for example, to stablize the frequency, or frequencies, of oscillation of the laser at or in a known relationship to the center of the atomic transition line at which the laser action occurs.
