Guideline For LASER Diode Driver

For the driving of the LASER diodes (LD) special drivers

circuits are used.

Ways

1. Produce constant regulated voltage

2. Produce constant current driven through the

LD load.

Uses Of Laser Diode

Laser diodes find wide use in telecommunication as easily modulated and easily coupled light sources for fiber optics communication.

Laser diodes use in barcode Laser diodes use in barcode readers.readers.

Many applications of diode lasers primarily make use of the "directed energy" property of an optical beam.
