Treiberstufe für gepulsten Hochleistungs-Halbleiterlaser mit thyristorartigem Halbleiterschalter

摘要

A laser diode driver utilizes a monolithic semiconductor device comprising an energy storage capacitor and an optically activated, thyristor-like structured p<+>-n-i-p-n<+> semiconductor switch integrated onto a single substrate. The capacitor is charged from a power supply, and a control unit then triggers a laser diode to trigger the thyristor-structured switch producing a very fast rise and fall pulse at high prf to a laser diode array. <IMAGE>
