High Power Pulsed Laser Diode Driver Circuit

For the driving of the laser diodes ld special drivers circuits are used.

High power pulsed laser diode driver circuit. The second type is more easy to design and us. Depends on application laser chosen at different range nm nano meter wavelength and watts. The hybridization of the driver permits much narrower pulse widths and faster rise times at lower voltage requirements than discrete laser drivers. The model 774a is a highly efficient low voltage dc input power converter laser diode driver designed to supply pulsed high current for laser diode stack loads.

As its structure is simple and easy to understoand and realize the circuit is of great value to be used to drive pulsed semiconductor laser. Pulsed output current is 200a with 45μs risetime into diode stacks of 24v to 40v at an average power to the load of 27w at 20hz. The lhcvn series is compatible. 60 amps 15 volts 600 watt high power laser diode driver module compact analog interface lacosys laser control systems gmbh 1139 00 0 3 amps 20 volts 300ma ten channel compact laser diode driver luzwavelabs.

In this project laser diode driver circuit is developed. Laser light amplification by stimulated emission of radiation and laser diodes are widely used in different domain applications it gives focused light ray in visible spectrum and laser diodes will perform good in regulated constant current. One of the things a user wants to know is how to size the high voltage power supply. Keywords laser diode driver narrow pulse high peak current current pulse 1 introduction with the advantages of small volume high efficiency long useful time and low cost pulsed laser diode is.

A high power laser diode driver is 5 amps and up to 100 s of amps in a cw mode. In a compact package. 2 produce constant current driven through the ld load. The lhcvn series incorporates a pulsed laser firing circuit into the same package as the laser diode.

These are by no means standards just a generalization based on the author s experience in the laser diode controller world. 1 produce constant regulated voltage. For fixed narrow width pulsed current drivers pco 7110 pco 7810 the power is in the pulse edges. The pulse of the future pco 7120 pulsed laser diode driver module compact economical oem module 5a to 50a output 9ns rise time variable pulse width from 12ns to 1µs repetition frequency to 1mhz diodes may be mounted directly on the pco 7120 eliminating the need for interconnect cables or striplines.
