Abstract
A system includes a planar waveguide that includes an active gain medium configured to receive pump light from a pump source and amplify stimulated emission light. The planar waveguide has a fast axis and a slow axis and is configured to operate in single mode in the fast axis and multimode in the slow axis. The system also includes a hybrid spatial filter configured to receive the amplified stimulated emission light from the planar waveguide and output laser light. The hybrid spatial filter includes a physical slit having a narrower dimension corresponding to the slow axis of the planar waveguide. The physical slit is configured to reduce an intensity of the amplified stimulated emission light received from the planar waveguide. The hybrid spatial filter also includes a Volume Bragg Grating (VBG) configured to constrain an angle of the amplified stimulated emission light and enable compact geometry intra-cavity beam expanding/collimating optics.
