The PCX-7450A is an air-cooled, high power pulsed current source designed to drive diode lasers, bars and arrays. It delivers current pulses variable from 20 A to 150 A, pulse width variable from 15 ...

A previous Design Idea describes an astable multivibrator that gets hysteresis from the positive feedback stage using a technique you can characterize as positive-capacitive feedback (Reference 1). It ...

Attosecond pulses enable sub-femtosecond studies of ultrafast electron dynamics. Since 2001, pulse durations have shortened ...
