Description

This dichroic RGB Beam Combiner is a compact opto-mechanical units that combines three fiber-coupled sources with different wavelengths into a common output fiber cable with high efficiency.

Optical Setup
The input ports are fiber-coupled to PM fiber cables or to SM fiber cables.
The different wavelengths are superimposed by means of dichroic mirrors. A summery of typical splitters can be found here.

Fiber Couplers
A fundamental component of the fiber-coupled Beam Combiner is the Laser Beam Coupler, which is the input into the opto-mechanical unit collimating the input radiation, respectively and, finally, couples the radiation back into the polarization-maintaining or single-mode fiber cable. The stability of the total fiber-coupled Beam Combiner is determined by the stability of the laser beam coupler.
