Industry Output coupler
In its most common form, an output coupler consists of a partially reflective mirror, sometimes called a beamsplitter. The reflectance and transmittance of the mirror is usually determined by the gain of the laser medium. In some lasers the gain is very low, so the beam must make hundreds of passes through the medium for sufficient gain. In this case the output coupler may be as high as 99% reflective, transmitting o
