Abstract: A dye laser is disclosed wherein a plastic disk containing laser dye is moved within a cylindrical race relative to a stationary pumping laser beam such that the pumping beam effectively scans the surface of the laser disk along a cycloidal path as the disk rolls along the race surface. The cycloidal illumination pattern on the disk enables a significantly increased amount of laser material to be exposed to the pumping beam.

Abstract: A laser diode pumped laser has a laser diode wavelength sensing and control apparatus. A laser medium is mounted in a laser cavity and has a laser diode pump having a laser diode or laser diode array having an output of a predetermined wavelength for exciting the laser medium. An optical radiation detector is coupled to the output of the laser medium to receive and measure the radiation from the laser diode transmitted through the laser medium and a detector bias and signal measurement circuit is coupled to the optical radiation detector to receive signals therefrom and generate an output signal responsive to the optical radiation detector signals and to apply the generated signals to the laser diode power supply (or to diode heaters) to vary the power supply output to vary the laser diode wavelength to maintain the laser diode wavelength at the absorption peak of the laser medium. A method of sensing and controlling the laser diode pump wavelength for a laser includes selecting a laser in accordance with the apparatus and coupling the selected detector bias and signal measurement circuit to the optical radiation detector to receive signals therefrom and generate output signals responsive to the optical radiation detector signals and coupling the radiation bias in the signalling measuring circuit to the laser diode power supply to vary the diode power supply output to vary the laser diode wavelength to maintain the output near the absorption peak of the laser medium.

The compartment cover can be made of a porous silica. A method of cleaning a laser optical cavity includes forming the housing having the cavity therein, selecting a decontaminate material, placing the selected decontaminate material into the housing, and forming and attaching a cover, at least a portion of which is porous to predetermined gases used in laser optical cavities, and attaching the housing with the selected material in the laser cavity so that selected contamination in the laser system optical cavity gas is absorbed by the selected material.

Abstract: The output of a laser oscillator is doubly passed through a birefringement medium, a quarter-wave plate and a laser amplifier by reflection from a phase conjugate mirror, the birefringent medium being between the oscillator and the plate in the path of the initial and reflected oscillator output. The birefringent medium divides the oscillator output into a first set of orthogonal polarization components (rays) and refracts one of them at a first angle successively through the plate and amplifier for reflection from the mirror through the amplifier, plate and medium. The reflected ray is amplified and then divided by the medium into a second set of orthogonal ray components which exit the medium at different angles away from the oscillator. In another embodiment, a second quarter-wave plate is added between the amplifier and mirror, and in a third embodiment the amplifier is positioned between the oscillator and the birefringent medium. These designs represent a unique means of separating in angle the oscillator input beam and the phase-conjugated/amplified beam. This results in a physical positional separation of the two, which allows the latter beam to be readily extracted and utilized in a useful fashion, and prevents potentially damaging reflections from being fed back into the oscillator.

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 conduction cooled solid state laser comprises a laser rod and a pump lamp within a pump cavity in a housing constituting a heat sink, the remote exterior surfaces of the rod and lamp being covered by highly reflective metal foils in intimate contact with those surfaces and backed by a thermally conductive material between the foil and housing that is selected to provide a tailored thermal impedance. The foil acts as a highly efficient reflector and as a thermal contact element between the heat source (rod or lamp) and backing material, the latter, in either solid or fluid form, being selected to provide the desired thermal impedance between the source and sink to optimize component temperatures. The optically reflective and the heat transfer functions of the 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.
