摘要： A laser apparatus for producing a laser light beam can include a gain medium; a pump light source to provide a pump light beam to the gain medium; a first reflector disposed between the first gain medium and the first pump light source and spaced apart from a gain portion of the first gain medium; a second reflector; and an output coupler. The first reflector is substantially reflective to the laser light beam and substantially transmissive to the pump light beam. The first and second reflectors and the output coupler define a folded beam path having a first portion and a second portion. The first portion of the beam path extends from the first reflector to the second reflector through the gain medium and the second portion of the beam path extends from the first reflector to the output coupler through the gain medium. The first and second beam paths define, within the gain medium, a non-zero folding angle. Optionally, the laser apparatus can include a second pump light source that can pump the same, or a second, gain medium.

摘要： Laser cutting and sawing can be performed on a variety of materials, transparent or non-transparent, including quartz, sapphire, glass, semiconductors, and diamonds. By direct generation of a special laser beam from a laser cavity and/or by shaping of a laser beam, unique characteristics of the beam in X- and Y-axes are utilized in the cutting and sawing of materials. Such a method and apparatus can reduce breakage and weight loss of the processed material while maintaining or increasing the cutting/sawing throughput.

摘要： In a solid state, Q-switched laser oscillator of the type in which the laser medium emits unpolarized light and the acoustooptical Q-switch exhibits strong optical polarization dependence, a first quarter-wave plate disposed within the optical cavity between the Q-switch and one cavity mirror for causing the polarization components of the light beam resolved along the fast and slow axes of the quarter-wave plate to rotate 90* between successive passages through the Q-switch so that the light which was less strongly scattered during one passage through the Qswitch is more strongly scattered during the next passage through the Q-switch, and a second quarter-wave plate disposed within the optical cavity on the other side of the Q-switch for nullifying the effect of the first quarter-wave plate when the Q-switch is turned off so as to leave the polarization components of the laser oscillation unperturbed. This invention relates to laser Q-switches, and, more particularly, to acousto-optical Q-switches for solid state laser media of the type which inherently produce unpolarized light.

摘要： Apparatus for scribing semiconductor wafers including a laser, focusing optics and a drive mechanism for moving the focal spot of the laser beam along a prescribed path on the surface of a semiconductor wafer. Globules of material ejected from the wafer by the action of the laser beam are prevented from falling back upon the surface of the semiconductor wafer or from depositing on the focusing optics by a vacuum device which draws in air from the region of the focal spot together with entrained globules of semiconductor material, or by a transparent film disposed parallel to and slightly spaced apart from the surface of the semiconductor wafer to catch the molten globules of semiconductor material, or by coating the semiconductor wafer with a substance which prevents the ejected globules from sticking.

摘要： A simple, lightweight, inexpensive laser proximity warning system for aircraft operating under visual flight rules (VFR) conditions. Mounted on each fully equipped aircraft is a laser transmitter, a detector sensitive to laser radiation and a retroreflector. The laser transmitter and detector periodically scan a predetermined region of the space surrounding the aircraft. If another aircraft equipped with a retroreflector is within the predetermined region, the transmitted laser radiation will be returned to the detector which will activate an indicator in the cockpit to warn the pilot of the presence and approximate bearing of the other aircraft.

摘要： An apparatus and method to measure optical intensity and phase of one or several light pulses is described. The apparatus combines a spectrally resolved interferometric asymmetric single-shot optical autocorrelator and imaging spectrograph. The asymmetric design of the optical autocorrelator based on second harmonic generation eliminates time-direction ambiguity, while a spectrally resolved interferometric pattern allows the performance of self-check and self-calibration of the apparatus and substantially improves convergence, robustness and reliability of the computational retrieval algorithm.

摘要： An acousto-optical device for intermittently transmitting a light beam including a body of photoelastic material shaped to provide resonant paths of different lengths for one or more beams of acoustic waves, each of which is periodically interrupted for predetermined time intervals. The light beam, which is normally scattered by interaction with the acoustic beams, is transmitted through the body of photoelastic material only when the interrupted intervals of all acoustic beams coincide simultaneously with the light beam.

摘要： A high power Nd:YLF solid state laser is constructed by placing a plurality of Nd:YLF solid state rods (11, 12) in series within a laser resonator. Each rod (11, 12) is mounted in a pumping chamber for providing laser action. A spherical lens (13) may be incorporated within the resonator as required for establishing with the resonator mirrors (14, 15) a large intra-cavity beam diameter. A cylindrical lens is provided within the resonator as a separate element or combined with the spherical lens (13) to compensate for astigmatism in the thermal focusing of Nd:YLF rods. Alternatively, the rods may be used in pairs with a half-wave plate between them to provide for compensation of astigmatism. A laser capable of high TEM00 mode output power may be achieved by these arrangements.
