Abstract: An optical crystal can be mounted to a mounting block configured to receive the crystal. A base portion on the mounting block utilizes two walls forming a corner and a single biasing spring clip to secure the crystal. The spring clip applies forces in two different directions substantially orthogonal to the two walls. The spring clip is based off a symmetrical geometry which applies nearly the same force application in both directions. The spring also features bend regions that contact the crystal in such a way as to reduce the presence of point loads or stress risers. The length of contact along the crystal is maximized, allowing for proper force distribution and a sufficient surface are contact for static holding capabilities.

Abstract: A universal fiber optic connector includes a housing and a fiber attachment element configured to attach an optical fiber in the housing. The attachment element positions the optical fiber such that an end face of the fiber is held within the housing. The fiber end face is positioned such that a beam of light emerging from the fiber end face has a defined wavefront located at a specified interface.

Abstract: An optical fiber connector apparatus may include a ferrule having a hollow through its center. The hollow is sized and shaped to receive an optical fiber such that an end of each of the optical fiber is located at an endface of the ferrule. The endface of the ferrule is partitioned into a first section and a second section. The first section is perpendicular to an axis of the ferrule and the second section is angled with respect to the first section. When the connector is assembled, the ferrule can butt couple to a similarly configured second ferrule such that the perpendicular second portions of the endfaces of the ferrules are physically touching. The angle of the angled portions sets a distance between portions of the endfaces corresponding to endfaces of optical fibers received in the ferrules thereby setting a gap between the fiber endfaces.

Abstract: A nonlinear optical crystal can be mounted to a mounting block configured to receive the crystal. The crystal can be mounted to the mounting block with a face of the crystal abutting a surface of the mounting block. An adhesive secures the crystal to the mounting block by adhering to the bottom and/or sidewall of the channel and to at least corresponding a portion of the bottom and/or side face of the crystal proximate an edge of the crystal.

Abstract: Control of average wavelength-converted power and/or wavelength converted pulse energy is described. One or more seed pulses may be generated and amplified with an optical amplifier to produce one or more amplified pulses. The amplified pulses may be wavelength converted to produce one or more wavelength converted pulses characterized by an average wavelength-converted power or pulse energy. Wavelength-converted power or pulse energy may be controlled by adjusting wavelength conversion efficiency without substantially changing the amplified power or pulse energy. Average wavelength-converted power may be controlled over a time scale comparable to a pulse period of the amplified pulses without adjusting an average power of the amplified pulses over the time scale comparable to a pulse period of the amplified pulses.

Abstract: Methods and apparatus for reducing a thermal load on an optical head are described. Waste light is captured at one or more locations in the optical head and directed to a location that is thermally isolated from the one or more locations in the optical head using or more optical fibers.

Abstract: Laser apparatus and methods involving multiple amplified outputs are disclosed. A laser apparatus may include a master oscillator, a beam splitter coupled to the master oscillator, and two or more output heads optically coupled to the beam splitter. The beam splitter divides a signal from the master oscillator into two or more sub-signals. Each output head receives one of the two or more sub-signals. Each output head includes coupling optics optically coupled to the beam splitter. An optical power amplifier is optically coupled between the beam splitter and the coupling optics. Optical outputs from the two or more output heads do not spatially overlap at a target. The master oscillator signal may be pulsed so that optical outputs of the output heads are pulsed and substantially synchronous with each other.
