Lawrence Livermore National Laboratory (LLNL) has installed and commissioned the highest peak power laser diode arrays in the world, representing total peak power of 3.2 megawatts (MW).
To drive the diode arrays, LLNL needed to develop a completely new type of pulsed-power system, which supplies [...]

Growth of InGaN multiple quantum wells and GaN eplilayer on GaN substrate
We investigated that the surface morphology of GaN epilayers was significantly affected by the surface tilt orientation of GaN substrate. Surface morphologies of GaN epilayers on GaN substrates show three types: mirror, wavy, [...]

High-power broad-area InGaNAs/GaAs quantum-well (QW) edge-emitting lasers on GaAs substrates in the 1200 nm range are reported. The epitaxial layers of the InGaNAs/GaAs QW laser wafers were grown on n+-GaAs substrates by using metal-organic chemical vapor deposition (MOCVD). The thickness of the InGaNAs/GaAs QW layers [...]
The dependence of the morphology and crystallinity of an amorphous Ge (a-Ge) interlayer between two Si wafers on the annealing temperature is identified to understand the bubble evolution mechanism. The effect of a-Ge layer thickness on the bubble density and size at different annealing [...]
