A laser diode apparatus has a first waveguide layer including a gain region connected in series with a second waveguide layer with a second gain region. A tunnel junction is positioned between the first and second guide layers. A single collimator is positioned in an output path of laser beams emitted from the first and second waveguide layers. The optical beam from the single collimator may be coupled into an optical fiber.

Dual junction fiber-coupled laser diode and related methods

Systems and methods for preventing image capture and exploitation by optically transmitting a disruptive effect to a digital imaging system. The disruptive effect interferes with the algorithms used to compress and analyze digital images and can be used to disable the imaging equipment or inject foreign code into the imaging system or image processing computer.

System and method for optical and laser-based counter intelligence, surveillance, and reconnaissance

A laser diode array having a plurality of diode bars bonded by a hard solder to expansion matched spacers and mounted on a gas or liquid cooled heatsink. The spacers are formed of a material such as copper/diamond composite material having a thermal expansion that closely matches that of the laser bars.

Liquid cooled laser bar arrays incorporating diamond/copper expansion matched materials

A laser diode array is formed on a heat sink having an insulating layer in which a plurality of grooves is formed through the ceramic layer and to or into the heat sink. A laser diode stack is soldered to the ceramic layer.
