    Abstract: A large number of passes of pump light through an active mirror in a solid state disk laser is realized using a pair of coupled imaging systems, where the optical axes of imaging systems are not coincident. Two imaging systems are optically coupled, so that an image of the first imaging system is an object of the second imaging system, and vice versa. An active mirror is disposed at the object or image plane, or at the focal plane of any one of the coupled imaging systems, where the position of the reflected pump beam during the multi-reflection between the first and second imaging systems is substantially unchanged.

    Abstract: A thin disk laser includes a thin disk of a host material incorporating a laser gain medium. The disk has opposite first and second surfaces, at least one of which is non-planar. The first surface is coated with a high reflectivity coating. The second surface has an anti-reflection coating thereon. The shape and mounting of the laser is such that mismatch of the coefficients of thermal expansion between the disk laser and the mount does not affect scaling of the laser to larger size disks for higher power lasers

    Abstract: A method for reducing speckle noise of a monolithic microchip laser with intracavity beam combining and sum frequency mixing is based on time averaging of uncorrelated speckle patterns generated from a large number of independent longitudinal modes and comprises schemes including selection of gain media and nonlinear optical materials to support broadband sum frequency mixing; adoption of gain-conjugated and/or chirped mirrors for flat-top spectra and/or mode phase diversification; multimode laser operation introduced by RF modulation; and multiplication of source modes in frequency mixing process featured with degeneration free and narrowed/uneven intervals. A device and an apparatus for generating low speckle noise red, green, blue lasers adaptable for color display systems are developed based on the inventive method.

    Abstract: A laser oscillator is provided that makes it possible to stably obtain a laser beam output in continuous or pulsed oscillation that has an intensity distribution of a top-hat profile or a fundamental transverse mode profile. An optical resonator is used that maintains the polarization of a laser beam traveling in the resonator but rotates the transverse mode pattern thereof. The resonator can be a ring resonator that includes an image rotating element, a nonplanar ring resonator, a diagonally crossed right-angle prism resonator or other such resonator. A combination of a polarizer, and a half-wave plate or Faraday rotator is used to preserve the polarization in the resonator. The optical path of the laser resonator can be intersected with another resonator of a conventional Fabry-Perot or planar ring resonator, and the optical paths coupled, using a beam-splitter or polarizer. A laser output beam from a counterclockwise or clockwise traveling wave in the laser oscillator is reflected back into the resonator by a reflector, suppressing such traveling laser oscillation.

    Abstract: A solid state laser module for amplification of laser radiation. The module includes a laser gain medium having a pair of generally parallel surfaces that form a disc-like shape, that receive and transmit laser radiation. At least one undoped optical medium is disposed adjacent a peripheral edge of the laser gain medium and in optical communication therewith. A source of optical pump radiation directs optical pump radiation into the undoped optical medium generally normal to the parallel surfaces and the undoped optical medium transports the optical pump radiation into the laser gain medium to pump the laser gain medium to a laser transition level. Alternative embodiments include arrangements for directing cooling fluids between adjacently disposed laser gain media.
