Abstract: The efficiency of an optically pumped solid state laser is substantially improved with a controlled geometry fluorescent converter between the pump light source and the lasing medium. Fluorescent materials have the capability of absorbing broadband pumping radiation, shifting it in wavelength and re-emitting it in the absorption band of the selected solid state laser medium. Use of angular formations having the converter surface facing the laser medium reduces fluorescent light trapping within the converter due to internal reflection thereby greatly increasing the total light output of the converter and thus the efficiency of the laser.

Abstract: The exterior surfaces of a laser rod and pump lamp are covered with a highly reflective metal foil to prevent light leakage from the rod and lamp. The laser rod and pump lamp operate within a cavity inside a heat sink. Between the metal foil and the housing is a thermally conductive fluidic material selected to provide a tailored thermal impedance between the heat sink and the rod and pump to optimize the steady state temperatures of these components. The conductive fluid is not circulated but is contained to act as a simple heat conductor. The optically reflective and the heat transfer functions of the laser pumping operation are essentially separate from each other, enabling selection of materials for these respective functions to enhance performance of the laser and substantially simplify its construction.

Abstract: A pulsed or CW laser is rapidly switched to operate at one or more selectable wavelengths by means of intracavity insertion of beam dispersion and focussing elements and an apertured focal plane mask and shutter assembly. The laser beam has an axis and is dispersed into components or sub-beams having different axes and representing different wavelengths, the sub-beams being focussed to substantially reduced diameters on the focal plane mask at points, respectively, at which apertures are formed. Movable shutters adjacent to the respective apertures control alternate opening of and closing of the apertures and selectively permit the laser to resonate at at least one of a plurality of wavelengths corresponding to that of the sub-beam passing through an open aperture. Mask apertures having very small diameters (

Abstract: A laser electrode assembly comprises an elongated bar having a plurality of longitudinally spaced sockets and is removably secured to a carrier which is anchored to the laser base and has a like number of plugs resiliently press-fitted within the sockets, respectively. Each plug has opposed sides to which are fastened a plurality of outwardly curved resilient fingers extending parallel to the direction of insertion of the plugs into the sockets. Each socket has a width less than the overall width of the plug and finger combination so that the fingers resiliently frictionally engage the bar within each socket. The bar is readily removed from the carrier for maintenance and repair purposes by prying the former from the plugs without necessitating removal of screws or bolts and thereafter passing the bar through the window opening aligned with the discharge gap.

Abstract: A lasing apparatus includes a laser medium and a pump source. The laser medium includes one of a Holmium-doped fluoride crystal or a Holmium-doped fluorozirconate ZBLAN glass fiber. The pump source generates pulses that resonantly pump the laser medium such that the laser medium produces an output from the 5I5 level to the 5I7 level of Holmium. The pump source produces pulses having a duration that is at least as long as a storage time of the 5I5 level of the laser medium. The pump source pumps the laser medium with signals having a wavelength shorter than 1.67 μm, with the laser medium producing an output having a wavelength of about 1.67 μm.

Abstract: A microlaser is provided that has a microresonator and a pump source for side pumping the microresonator. The microresonator includes an active gain medium and a Q-switch that extend lengthwise between the opposed end faces of the microresonator. The pump source is therefore positioned so as to introduce pump signals into the microresonator via the side surface that is adjacent to and defined by the active gain medium. By side pumping the microresonator, the microlaser can generate a series of pulses having greater pulse energies and greater average power levels than the pulses provided by conventional microlasers. In addition, the side pumped microlaser can also generate pulses having greater pulse widths than the pulses provided by conventional microlasers of a similar size. As such, the side pumped microlaser can be employed in more demanding applications that require pulses having greater pulse widths as well as pulses that have greater pulse energy and greater average power than are typically provided by conventional end pumped microlasers.

Abstract: A boresight alignment method is used for aligning a laser with an optical sighting system in a laser designator or the like. The method includes selecting a target formed of a flat sheet of material, such as a metal foil, supporting the selected target at the focus of a collimating telescope in the path of a laser beam of a laser and optical sighting system combination, such as in a laser designator, focusing the laser beam onto the one side of the target, and burning an aperture in the target with the laser beam. The method includes illuminating the target burned aperture from the rear thereof with a visible light or with an infrared source and then aligning the optical sighting system with the illuminated target aperture. Both the day and night viewing optics can be aligned by providing pinhole illumination with multi-spectral target pinhole illumination. The target may be mounted so that it can be rotated to provide successive alignments of the same or different laser optical sighting systems. The target can be an aluminum foil supported on a metal frame or with a paper or polymer backing. An optical sighting system can be aligned to a laser with high accuracy under rugged military and industrial field operating conditions.

Abstract: A laser apparatus is described having multiple modes of operation using intracavity optical switching within a laser resonator. The laser resonator has a solid state gain medium and one or more optical switches located between a pair of end reflectors. The pump for the gain medium has controlled duration to allow varying the pumping energy and pulse repetition rate. The laser has a Q-switched mode for generating energy from the laser resonator at a fixed level of outcoupling when the laser pump is operated to produce a range of predetermined pulse, rates and durations. The laser also has a cavity dumped mode of operation in which the laser pump is operated to produce a second range of predetermined higher pulse repetition rates and shorter pulse durations so that the pulse energy, rate and duration are selected by first Q-switching with essentially no outcoupling and then rapidly cavity dumping all the optical energy in the resonator. Intracavity optical switching of the laser resonator is used to achieve the two distinct modes of operation, the first being conventional Q-switched operation with pulse width equivalent to several cavity round trip times and the second being Q-switched cavity, dumped operation with pulse width equivalent to about one cavity round trip time. Use of this apparatus with external frequency shifting optics is also described.

Abstract: A method and apparatus for testing materials for use in a laser resonator includes selecting a test fixture apparatus having a housing with an internal chamber volume selected to approximate the internal volume of a predetermined laser resonator and having a pair of sealed windows therein which are removably attached to the housing and having optical coatings selected to match the coating on the optics of a laser. The housing has a removable cover and a gas purging opening. A laser of a predetermined wavelength and power is mounted adjacent the test fixture and is aligned for directing the laser beam through both of the windows of the test fixture. A material is placed in the test fixture and a laser beam directed through the coated windows for a predetermined period of time and thereafter the coated windows are examined for damage or contamination. The test fixtures are also cleaned and certified prior to testing so that a preselected test fixture can determine damage for selective materials used therein.
