Circuit provides laser-diode control - 19-Sep-02 Issue of EDN
Laser diodes are sensitive to ESD, rapid turn-on currents, and overvoltage
conditions. To address those problems, the simple laser-diode controller in
Figure 1 has several functions. The first part of the circuit comprises an
8.2V zener diode, D1 that forms the heart of a constant-voltage source for
the laser diode..... [Design Idea by Michael Fisch, Agere Systems, Longmont,

Current Sources for Fiber Optic Lasers - AN90 Linear Technology A
large group of fiber optic lasers are powered by DC current. Laser drive is
supplied by a current source with modulation added to the signal. The
current source, although conceptually simple, constitutes an extraordinarily
tricky design problem. There are a number of practical requirements for a
fiber optic current source and failure to consider them can cause laser
and/or optical component destruction. This application note describes
ten laser current source circuits with a range of capabilities. High and low
current types are presented, along.....
HeNe Laser Power Supply (Aaron Cake) - If you have ever worked with lasers,
you know how fun and interesting it can be, you also know how expensive it can be. The
high voltage power supplies for the laser tubes are often more expensive then the
tubes themselves. This supply can be built with commmon parts, most of which you
probably already have in your junk box. The secret is the transformer used. It is a
common 9V 1A unit, connected backwards for step up..... [Design by Aaron Cake]
Home Built Laser Projector - Laser projector is one of the laser display
equipments. This project builds the closed-loop galvos mainly and aiming at
professional grade. (added 10/05)
