Abstract:

Diffraction limited, single narrow lobe radiation from a large area laser is achieved in a system using an external ring laser cavity to return radiation to the laser via a spatial filter and a Faraday rotator. An antireflectance coating of sufficiently small reflectivity added to the large area laser converts it into a laser amplifier which provides optical gain in a ring laser cavity.
