A generally accepted fact about relays and solenoids is that after they’re driven into the actuated state, only half as much coil voltage and therefore only one fourth as much coil power, are required ...

Abstract: An auto laser power control (APC) circuit for optical communication laser diode driver (LDD) is proposed. The APC compensates the fluctuation of (laser diode) LD laser power, maintains the ...

A single laser-diode driver from Elantec Semiconductor directly drives both CD and DVD lasers, simplifying the task of combining these optical drives in a single system. Elantec's patented EL629XC ...

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, and decided to show us how it operates, tells us what we should keep in mind when designing such a driver, and talks about ...

See this diagram,I've been told the the proprietary drivers offer some extra protection from very short spikes (on power up and shutdown) in the current which laser diodes are very sensitive to and ...

The PCX-7451 is a high power pulsed current source featuring microprocessor-controlled front panel and RS232 interface that provides individual control of each function, while the backlit display ...

Newport Corporation introduces Laser Diode Control Kits which include a laser diode driver, a temperature controller, a laser diode mount, cables, and accessories. The new control kits enable quick ...
