Gas cooled faraday rotator and method
Abstract
To enable several orders of magnitude increases in average power and energy handling capability of Faraday rotators, the technology utilizes high speed gas cooling to efficiently remove thermal loading from the Faraday optic faces while minimizing the thermal wavefront and thermal birefringence by creating a longitudinal thermal gradient. A recirculating gas cooling manifold accelerates the gas over the surface of the slab to create a turbulent flow condition which maximizes the surface cooling rate. The technology further provides a spatially uniform thermal profile on the Faraday slabs.
