Mode Cleaners

Devices which can improve the Beam Quality of Laser beams.

Due to various reasons, laser beams often have a non-perfect beam quality, i.e., distortions of their Intensity and/or phase profile. Depending on the circumstances, various types of “mode cleaner” devices may then be used for “cleaning up” the beam profile.There are resonant and nonresonant types of Mode cleaners, which are very different concerning operation principle and the Range of application.
