Laser module

A laser module (laser diode module) is a device consisting, as a rule, of a laser diode , optical components that form laser radiation, and an electronic component that powers and controls the laser diode.

Depending on the purpose, the laser module radiation can be collimated or focused, take the form of a point, line or a set of lines, a cross, a circle, a grating, etc. The wavelength of the module varies from ultraviolet to mid-IR. The radiation power can be constant or modulated by digital or analog signals. In certain cases, to preserve the radiation wavelength or output power with high accuracy, the module can be equipped with a thermal stabilization system for the laser diode. The same mechanism can be used to adjust within small limits of the operating wavelength of the module. These are just the basic parameters of the laser module. The full list of parameters is much longer and in practice in each case is determined by the consumer of the module.
