DOE fine tuner for lasers

11th January 2016

For many applications there is a need to fine tune the output parameters of the laser, with diffractive optical elements the laser output can be controlled very precisely but without flexibility. Holo/Or has developed a new solution - a DOE tuner for wavelengths between 266 and 1,064nm.

Depending on the type of diffractive element, the tuner module can be placed before or after DOE. The basic principle is to finely adjust the beam diameter - this in turn can adjust the spot size or, in the case of multi-spots, the separation angle.
