Laser Diode Modules

You can buy laser diode modules from:

Definition: modules containing diode lasers, and possibly also some optics, cooling devices, electrical elements, etc.

Laser diodes are often used in the form of laser diode modules, i.e. packages which contain one or several laser diodes, in most cases combined with some optics and electronics. Such modules are much easier to use than plain laser diodes, as they serve a number of functions:

Applications of laser diode modules include precise pointing and alignment of optical elements, printing and imaging systems, displays, bar code scanning, optical data storage, optical sensors, pumping of solid-state lasers, open air communication, and medical applications (e.g. photodynamic therapy, ophthalmology).

There are also laser pointers, which can be considered as laser diode modules with integrated batteries, normally used as hand-held devices.

cover of print encyclopedia

Since October 2008, the Encyclopedia of Laser Physics and Technology is also available in the form of a two-volume book. Maybe you would enjoy reading it also in that form! The print version has a carefully designed layout and can be considered a must-have for any institute library, laser research group, or laser company.

You may order the print version via Wiley-VCH.
