Many military applications require reliable laser diode operation across a wide range of elevated temperatures. Size, Weight and Power (SWaP) restrictions often limit cooling options and necessitate that high-power emission at the desired pump wavele

High-Power Diode Laser Technology XVI.
A low-SWaP (Size, Weight and Power) diode array has been developed for a high-power fiber-coupled application. High efficiency (~65%) diodes enable high optical powers while minimizing thermal losses. A large amount of waste heat is still generated a

A number of emerging applications of low-temperature co-fired ceramic (LTCC) require embedded fluidic structure within the co-fired ceramic and or precise external dimensional tolerances. These structures enable the control of fluids for cooling, sen

SiC VJFETs are excellent candidates for reliable high-power/temperature switching as they only use pn junctions in the active device area where the high-electric fields occur. VJFETs do not suffer from forward voltage degradation, exhibit excellent s

One of the primary challenges of the Laser Inertial Fusion Engine (LIFE) project and other similar projects around the globe is the cost and availability of the laser diode arrays needed to pump the solid-state laser gain media in the system. Current
