Product Features

End reflectors are key optical components in laser resonators.They usually has high reflectance of 99.5% or 99.7%. Because absorption in the coating is higher than in the output coupler, substrate materials, such as Ge or GaAs, with high thermal conductivity are used in most lasers.
