Gaussian mirrors from LASER COMPONENTS

The Gaussian mirror is based on a Fabry Perot interferometer with a position-dependent mirror spacing. A distance layer with variable thickness is surrounded by two identical mirror layers. If the spacing between the mirror layers is a multiple of λ/4, the system is transparent for that wavelength. If, however, the spacing is an odd multiple of λ/4, the total reflection is determined by the reflection of the mirror layers.

These Gaussian mirrors are used in unstable resonators where they help produce high-quality laser beams with low divergence at high pulse energies. In frequency-doubled systems, they are used to create greater pump efficiency.

We specialise in producing custom Gaussian mirrors to exact customer requirements. They are characterised using an innovative measuring system ensuring consistently high quality and precision.
