摘要： A housing for an optically pumped semiconductor (OPS) laser resonator is terminated at one end thereof by an OPS-chip. The laser resonator is assembled on a platform with the OPS-chip at one end of the platform. The platform is fixedly attached to a baseplate at the OPS-chip end of the platform. The remainder of the platform extends over the baseplate with a gap between the platform and the baseplate. A pump-laser is mounted directly on the baseplate and delivers pump radiation to the OPS-chip.

摘要： A modular solid-state laser comprises a diode-laser pump module and a laser-enclosure. The diode-laser pump module produces a collimated beam of laser-radiation for pumping a gain-element within the laser-enclosure. The beam of pump laser-radiation is focused into the gain-element by optics located within the laser-enclosure. The diode-laser pump module can be replaced or exchanged without realigning optics located within the laser-enclosure.

摘要： Plane-polarized laser-radiation from a laser-source is converted to circularly polarized radiation by a quarter-wave plate. The circularly polarized radiation is input into a hollow-core fiber for transport to a point of use. The transported radiation is converted back to plane-polarized radiation by another quarter-wave plate between the fiber and the point of use.

摘要： Laser-machining apparatus includes a carbon monoxide (CO) laser emitting a beam of laser-radiation having forty-four different wavelength components and optical elements for delivering the radiation to workpiece. An acousto-optic modulator is provided for modulating the beam on the workpiece. A birefringent plate is provided in the beam transported to the workpiece for randomly polarizing radiation incident on the workpiece. A minimum distance of the workpiece from the laser, and the number of different-wavelength components in the laser beam provides that no optical isolator is required for preventing feedback of radiation into the laser.

摘要： Optical apparatus for amplifying pulses in a pulsed laser-beam includes a pulse-stretcher having a single transmission-grating in a multi-pass configuration at a non-normal incidence angle. A regenerative amplifier amplifies stretched pulses in the laser-beam. A pulse-compressor including two spaced-apart reflection-gratings in a multi-pass configuration compresses the amplified pulses. Pulse-parameters of the compressed amplified pulses are optimized by iteratively adjusting the incidence angle of the pulsed laser-beam on the transmission-grating of the pulse-stretcher and the spacing between the reflection-gratings of the pulse-compressor.

摘要： A light-source includes a planar array of diode-laser bars and a plurality of turning-mirrors arranged to stack beams from the diode-laser bars in the fast-axis direction to provide a first combined beam. Six plane mirrors are arranged to divide the combined beam into three beam-slices, each having one-third the slow-axis width of the first combined beam, and add the beam-slices in the fast-axis direction to provide a second combined beam having about one-third the slow-axis width and three-times the fast-axis length of those of the first combined beam. A spherical mirror and a cylindrical mirror focus the second combined beam into an optical fiber.
