Instead of being marketed as complete laser systems, industrial lasers are usually sold as OEM laser modules. As a result, a Oem laser electronic slavers to one or more other producers who then combine them into larger gear, including laser material processing equipment. When this happens, each company can concentrate on its particular areas of accountability without needing to completely understand the system. In particular, understanding the nuances of how an OEM module functions internally shouldn't be frequently required of the integrator.

Oem laser module can contain gas lasers, lamp-pumped lasers, diode-pumped solid-state lasers, lamp-pumped solid-state lasers, and less frequently other kinds of lasers. Additional optical components for beam sizing and perhaps nonlinear frequency conversion may also be present in the housing. For instance, there are green laser modules that generate Nd: YAG laser beams that are frequency-doubled at the typical 532-nm wavelength. Another option is to send the light output as a free-space laser beam through an Er glass optical connection.

An OEM laser typically, has its own full enclosure, even if the device is to be integrated in a larger product with its own closed housing. This encourages even more labour separation between laser manufacturers and system integrators.

Characteristics of OEM Lasers

Well-defined optical interfaces are required for integration of lasers into larger systems. The specifications for OEM lasers are largely the same as those for other lasers. However, extra attention must be paid to the design of optical, mechanical, and electronic interfaces for straightforward integration into a Graded reflectivity mirror. The focus position, and beam quality of the generated laser beam, the electrical voltage and power requirements of the laser, the precise method for triggering laser pulses, and the technique for mounting the module on a base plate. Additional details regarding the dissipation of waste heat, such as the maximum power dissipated and the allowed base plate temperature, may be present.
