Laser-diode-pulsers


Posted on Feb 7, 2014

The laser diode ·pulser is a simple drive circuit capable of driving the laser diode with 10-A, 20-ns pulses. For a 0. 1 % duty cycle, the repetition rate will be 50 kHz. A complementary emitter follower is used as a driver. Switching speed is determined by the h of the bipolar transistors used and the impedance of the drive source. A faster drive

circuit is shown. It can suwly higher peak gate current to switch the IRF520 very quickly. This circuit uses a MOSPOWER totem-pole stage to drive the high power switch. The upper MOSFET is driven by a bootstrap circuit. Typical switching times for this circuit are about 10 ns for both tum-on and tum-off. We aim to transmit more information by carrying articles.
