Resistances of devices or samples of material can be measured accurately by placing the sample between conducting plates attached to an electrooptic crystal. The plates are then charged, and the voltage-induced birefringence in the crystal is monitor

We report the generation of high-energy, low-jitter, and short pulses by gain-switching of a tapered stripe gain- guided laser diode via resonant driving. The application in optically clocked sample-and-hold will be discussed.© (1998) COPYRIGHT SPIE

A two-channel digitized system for measuring small density and temperature fluctuations in turbulent air (e.g., in flow in a wind tunnel) is described. The method is based on the fact that ten rotational lines of the X(v" = 0) to B(v′ = 4) absorpti
