Explosive pulsed power consists of those devices that convert the chemical energy in explosives into electrical energy. In 2004, a series of programs were initiated to develop several types of very compact explosive pulsed power generators. Based on these recent efforts, we now have a better understanding of the weaknesses and strengths of these small generators. As a result, we can now build r...

Here we report a compact monolithic 2000nm pulsed laser with a single spatial mode output, ~1.5ns pulse duration, 8kW peak power and >200mW average power at 20 kHz repetition rate. The gain-switched laser, consisting of a pair of fiber Bragg gratings and 0.5m of thulium-doped single cladding fiber, was core pumped by a high peak power pulsed 1.5 m laser. When the input pulse energy of the 20 kH...

Before getting into the design of snubbers it is important to understand the waveforms which occur naturally in power circuits. These provide both the motivation for using snubbers and the information needed for their design. There are many different types of circuits used in power converters, motor drives, lamp ballasts and other devices. Fortunately all of these different circuits have a comm...

A high energy double-pulsed Ho:Tm:YLF 2-btm laser amplifier has been demonstrated. 600 mJ per pulse pair under Q-switch operation is achieved with the gain of 4.4. This solid-state laser source can be used as lidar transmitter for multiple lidar applications such as coherent wind and carbon dioxide measurements.

A pulsed power supply with a compact and low-cost electric-double-layer-capacitor (EDLC) is developed for generating magnetic fields long pulse duration of few seconds. The system demonstrated in three experimental setups using 10.7 F- or 50 F-EDLC capacitor bank. By the bank 27 mm wide-bore magnet, field peak strength 24.3 T ∼1 s generated. profiles are reproduced theoretical calculations taki...

Electrically pumped vertical cavity surface emitting lasers (VCSELs) can produce hundreds of mW's of 976 nm CW output in a TEM00 mode when operated with an external cavity configuration. During pulsed operation (<50ns) a significant increase in the peak power is observed, compared to CW operation. High peak powers makes these lasers very well suited for intra-cavity frequency doubling with a no...
