LASER COMPONENTS is one of the few manufacturers that can produce Gaussian mirrors (also known as graded reflectivity mirrors (GRMs)). The special coating is characterised by a degree of reflection that falls off in a Gaussian-shaped curve starting from the centre of the optic. Customers can choose almost any shape the Gaussian curve should take. The reflection values in the centre range from a few per cent to a maximum of 85%. Gaussian mirrors are extremely stable in the laser and suited for high power levels.
Applications
They are used, in particular, as output couplers in unstable resonators where they help to reduce the beam divergence at high pulse energies. They are also used to generate laser beams with a very homogeneous power distribution, which are required for illumination tasks, in material processing, or medical applications. To produce high pump efficiency, Gaussian mirrors are, furthermore, used in frequency-doubled systems.

In the past few years, manufacturing costs have been significantly reduced.
