In optical system, usually need to split one beam to two. The normal method is using the partially reflecting mirrors,
the beam goes through the mirrors, one part transmitted, another part reflected. One is used for reference beam, another one is used for testing beam. T/R is the splitting part ratio. Like R 50% and T 50% etc.
We will use high damaged coating layer HfO2/SiO2 for laser system.
