摘要： A gas-discharge waveguide CO2 laser has a Z-shaped folded waveguide formed by three ceramic tubes. Ends of the adjacent tubes are shaped and fitted together to form a common aperture. The tubes are held fitted together by spaced-apart parallel discharge electrodes. Four mirrors are arranged to form a laser-resonator having a longitudinal axis extending through the tubes.

摘要： A laser includes a traveling-wave ring-resonator in which one resonator mirror is a mirror of an interferometer arranged such that, when the interferometer is operated in an anti-resonant condition, the mirror has a greater effective reflectivity for clockwise circulation of light in the resonator than for anticlockwise circulation of light in the resonator. There is a difference between the clockwise and anticlockwise effective-reflectivity sufficient that lasing in the resonator is possible only in the clockwise direction.

摘要： A multi-laser module includes two compartments arranged one above the other. The lower compartment includes four lasers and four corresponding beam-steering mirrors arranged to direct corresponding laser beams into the upper compartment. The upper compartment includes a regular pentagonal prism and four other beam-steering mirrors each arranged to receive one of the laser beams and direct that beam to the prism. The beam prism has three dichroic-coated surfaces and two antireflection-coated surfaces. Each of three of the beams enter the prism via a corresponding one of the dichroic-coated surfaces. The fourth beam enters the prism via one of the antireflection coated surfaces, and all of the beams exit the prism via the other antireflection coated surface along a common path.

摘要： A frequency-doubled, edge-emitting semiconductor laser includes a separate confinement heterostructure surmounted by a waveguide including a converting layer of a periodically poled, optically nonlinear material. Fundamental radiation generated in the heterostructure is directionally coupled from the heterostructure into the waveguide, is converted to second-harmonic radiation in the converting layer and is delivered from the waveguide as output radiation. In one example, a distributed Bragg grating is included at an interface between the heterostructure and the waveguide for facilitating coupling of fundamental radiation from the heterostructure into the waveguide.

摘要： Laser apparatus is disclosed in which fundamental-wavelength optical pulses delivered from a mode-locked laser resonator at a pulse-repetition frequency (PRF) are converted to harmonic-wavelength pulses in an optical delay loop. One example is disclosed in which the harmonic-wavelength pulses are delivered directly from the delay loop. Another example is disclosed in which the harmonic-wavelength pulses are divided by the delay loop into a number of temporally spaced-apart replicas thereof, and the delay loop delivers bursts of replicas of different one of the harmonic wavelength pulses at a burst-repetition frequency equal to or a multiple of the PRF of the resonator.

摘要： A directly cooled diode-laser bar package includes a diode-laser bar bonded to a heat-sink. The operating temperature of the diode-laser bar can be selectively varied by varying the thermal impedance of the heat-sink in or near a region of the heat-sink on which the diode-laser bar is bonded. The thermal impedance is selectively varied by varying the insertion depth of screws inserted into corresponding screw holes extending into the heat-sink close to or immediately adjacent the region on which the diode-laser bar is bonded.

摘要： An electro-optical switch includes an optical assembly arranged to transmit laser-radiation. The optical assembly comprises an active optical crystal. On one of two opposite surfaces of the crystal is an optical window formed from a material having a refractive index lower than the material of the crystal. Heat deposited, as a result of transmission of the laser-radiation, at the surface of the crystal in contact with the widow is transferred to the window, thereby reducing the potential for optical damage to the crystal surface. The window is sufficiently thick that it has an odd integer multiple of quarter-wavelengths optical thickness at a wavelength about equal to a wavelength of the laser-radiation, thereby behaving as an antireflection device for the crystal at that wavelength. In one embodiment of the optical assembly, the active optical crystal is a cadmium telluride crystal and the window is formed from cesium bromide.
