Patent Number Title Of Patent Date Issued
6178040 Laser with two orthogonal zig-zag slab gain media for optical phase distortion compensation January 23, 2001
An optical amplifier for use with a solid state laser which includes a pair of elongated slabs of a solid state lasing material, such as a rare earth doped yttrium-aluminum-garnet (YAG) crystal. Two embodiments of the invention are disclosed. In both embodiments of the invention, each of
6069730 Phase conjugated master oscillator-power amplifier breakdown control May 30, 2000
A system and method for monitoring the mode of an input beam to a phase conjugated master oscillator power amplifier (PC MOPA). In order to prevent catastrophic optical damage to the MOPA components, the method and system shuts down the master oscillator when a multi-mode input beam is
6034977 Optical path difference control system and method for solid state lasers March 7, 2000
A method of controlling the thermal optical path difference (OPD) in a lasing medium in a solid state laser during pumping of a lasing medium 10 including a pair of side faces 12 for receiving radiation during pumping and a pair of edge faces 16, comprises the steps of determining a
5949805 Passive conductively cooled laser crystal medium September 7, 1999
There is provided an optically pumped laser apparatus 10 which includes a heat conductive assembly 14 which is affixed to a solidstate yag laser crystal medium for generating a laser beam 49 within the laser crystal medium 12. The heat conductive assembly 14 comprises a heat diffusing
5825791 Variable coherence length high brightness laser architecture October 20, 1998
A high power laser source having a preselected broad bandwidth, including a master oscillator providing a single-mode laser beam, a resonant electro-optical modulator and a source of radio-frequency (rf) modulation voltage, to produce a modulator output beam having sidebands spaced on
5818856 Ozone compatible stimulated brillouin scattering materials October 6, 1998
A device for producing phase conjugation of electromagnetic radiation using stimulated Brillouin scattering (SBS), comprising an SBS cell having a liquid perfluorocarbon as an SBS medium. The liquid perfluorocarbon is selected from the group of compounds having the formula C.sub.x F.sub.
5646773 Solid-state zig-zag slab optical amplifier July 8, 1997
A solid-state laser architecture producing a beam of extremely high quality and brightness, including a master oscillator operating in conjunction with a zig-zag amplifier, an image relaying telescope and a phase conjugation cell. One embodiment of the laser architecture compensates for
5640406 Birefringence compensated laser architecture June 17, 1997
Apparatus, and a related method, for compensating for birefringence introduced in a birefringent medium, such as a solid-state amplifier. The invention includes the combination of a quarter-wave plate, a Faraday rotator and a mirror, which may be a phase conjugation cell. Light passing
5555254 High brightness solid-state laser with zig-zag amplifier September 10, 1996
A solid-state laser architecture producing a beam of extremely high quality and brightness, including a master oscillator operating in conjunction with a zig-zag amplifier, an image relaying telescope and a phase conjugation cell. One embodiment of the laser architecture compensates for
5467214 Birefringence-compensated alignment-insensitive frequency doubler November 14, 1995
Apparatus and a related method for generating a second harmonic frequency optical output from a fundamental frequency input beam, without significant birefringence. The apparatus includes two Type II doubler crystals of equal length arranged with their corresponding axes parallel to
5216681 Highly-efficient solid-state blue laser June 1, 1993
A highly-efficient solid-state blue laser that exploits a strong emission line provided by a solid-state laser medium of neodymium-doped scandium oxide (Nd:Sc.sub.2 O.sub.3) to produce a beam of coherent blue light at a wavelength matching the absorption line of cesium at 455.6 nm (0.455
