Efficient polarised output from end-pumped multirod resonators

Polarised radiation is required for many applications in optics. This paper describes several laser designs based on the variable configuration resonator, each capable of producing polarised output in a multirod resonator. Schematics for the designs are given and the modes of each cavity considered along with the stability of each resonator. Slope efficiencies as high as 45% and optical efficiencies of over 35% were observed in polarised operation with output powers as high as 10.2 W.
