An infrared imager includes a first optical component, a second optical component, and at least one thin film dielectric layer. The first optical component has multiple first parallel conductors with a first spacing pattern, aligned in a plane perpendicular to an axis. The second optical component has multiple second parallel conductors with a second spacing pattern, aligned in a plane perpendicular to the axis, angularly offset from the first direction. The thin film dielectric layer includes a refractive index change (RIC) material disposed between and in contact with the first and second parallel conductors. The first optical component, second optical component, and at least one thin film dielectric layer form an antenna array configured to detect one or more predetermined infrared wavelengths based on at least one of the first spacing pattern or the second spacing pattern or the angular offset.

Nano-antenna array infrared imager

A system including a first refractive lens doublet comprising a first fixed focal length lens and a first liquid-based lens, the first liquid-based lens responsive to transition between a convex configuration and a concave configuration when electronically actuated, and a second refractive lens doublet comprising a second fixed focal length lens and a second liquid-based lens, the second liquid-based lens responsive to transition from a convex configuration to a concave configuration when electronically actuated. A focal length of the first liquid-based lens and a focal length of the second liquid-based lens are switched between a positive focal length and a negative focal length when electronically actuated to provide a net focal length to produce a varied collimated magnification of light.

System and method for converting between Keplerian and Galilean telescope magnification

An integrated, low profile, high power laser light emission device is disclosed. The integrated laser light emission device provides uniform heat dissipation, as well as uniform pumping of the laser gain medium without the need for a pumping cavity. The laser system includes a pump diode array that can be mounted directly to a laser gain medium without intervening correcting optics hardware. Heat generated by the laser light emission device is cooled by a single cooling system. In the laser device, a pump diode array is preferably a Vertical-Cavity Surface-Emitting Laser (VCSEL) array. VCSEL arrays are mounted on the laser gain crystal by a metal cavity frame or metal stilts. The slightly elevated mounting of the VCSEL's enables increased cooling and maximizing the quantity of VCSEL's on the laser gain medium in order to achieve highly efficient and high power laser light output.

Diode pumping of a laser gain medium

The present invention pertains to a composite slab laser gain medium with an undoped core and at least one doped gain medium section disposed on at least one side of that core. The gain medium is constructed so as to mitigate the effects of thermal and mechanical stresses within it and also allow for impingement cooling of the doped gain medium section.
