Power characteristics of planar index-antiguided waveguide lasers with transverse mode competition

Power characteristics of planar index-antiguided waveguide lasers with transverse mode competition

We report comprehensive analysis of output characteristics of homogeneously broadened index-antiguided slab lasers with transverse mode competition. Robust single fundamental mode operation is achieved when the distributive modal loss due to index antiguiding dominates the output coupling loss. Maxi...
