Abstract
A device for attenuating thermal lensing in an optical resonator is disclosed. The device includes a laser rod having an optical axis, a first high-reflectivity element disposed within a path of the optical axis, an outcoupling element disposed within a path of the optical axis, a second high-reflectivity element disposed within a path of the optical axis, and a potential source coupled to the second high-reflectivity element. Application of a first potential from the potential source onto the second high-reflectivity element causes the second high-reflectivity element to be substantially reflective, and application of a second potential from the potential source onto the second high-reflectivity element causes the second high reflectivity element to be substantially transmissive, to preserve a TEM beam quality within the optical resonator under varying thermal conditions.
