Patent Number Title Of Patent Date Issued
7230778 Sliding track for optical apparatus June 12, 2007
This sliding track for optical apparatus provides a system for mounting and easily moving lens cells and/or other portions of an optical apparatus that are co-axially arranged with respect to an optical axis of the apparatus along said optical axis while maintaining axial alignment.
7197059 Short wavelength diode-pumped solid-state laser March 27, 2007
A diode-pumped solid-state laser including a short wavelength (e.g., blue, violet, or UV) semiconductor laser that pumps an absorption transition in a rare-earth-doped material. Responsive to this pumping, the rare-earth active ion directly emits laser radiation. A number of different
7065109 Laser with narrow bandwidth antireflection filter for frequency selection June 20, 2006
A laser includes a narrow bandwidth AR coating for defining a frequency range for laser emission within the laser cavity. Advantageously, the narrow-band AR coating has a very low loss, which can be particularly useful if the gain medium has low gain. The narrow-band AR coating can be
6925234 Flexure apparatus and method for achieving efficient optical coupling August 2, 2005
An inexpensive, robust, and adhesive-free method and apparatus is disclosed for efficiently coupling first and second optical components together utilizing a flexure assembly for fine alignment. An initial three-dimensional rough alignment process positions the first and second optic
6724787 Low noise solid state laser April 20, 2004
A low noise laser includes a birefringent gain crystal arranged so that polarization is not constant within the gain crystal. The gain crystal and an intracavity optical element each have a nonzero polarization retardance. The total single-pass retardance is approximately equal to an
6389043 Efficient frequency-converted laser with single beam output May 14, 2002
An efficient frequency-converted solid state laser that outputs a single beam utilizing an angled reflector situated within the laser cavity. The laser comprises an optical cavity including a first reflector and a second reflector. A gain medium situated within the optical cavity is ener
6101201 Solid state laser with longitudinal cooling August 8, 2000
An optically-pumped laser comprises a laser cavity, a solid-state gain medium and an optically transparent heat sink (OTH) situated within the laser cavity. The gain medium and OTH are thermally coupled and at least one of the solid-state gain medium and the OTH has an etalon structure
5818632 Multi-element lens system October 6, 1998
A multi-element refractive/diffractive lens system, especially useful in an interferometer of the Fizeau type for forming a partially reflective end of the cavity and focusing collimated laser light at a focus in the cavity, uses a plurality of lens elements all of which are plano concav
5626157 Optical table May 6, 1997
A honeycomb tabletop, including a honeycomb core positioned between a top and bottom structural layer, wherein a number of cups are positioned between the bottom layer and the top layer, and at least some of the number of cups are sized and shaped to cooperate with the lower face of
5402734 Optical table having debris retention structures April 4, 1995
A honeycomb tabletop, including a honeycomb core positioned between a top and bottom structural layer, wherein a number of cups are positioned between the bottom layer and the top layer, and at least some of the number of cups are sized and shaped to cooperate with the lower face of
