Description/Abstract
A simple method for the production of a polarised Nd:Y3Al5O12 on Y3Al5O12 planar waveguide laser is reported. A 50nm layer of Au deposited on the surface of an unclad, 8.3 μm thick core region has produced an improvement in the TE/TM polarisation extinction ratio from 7dB to 27dB. The M2 of the beam in the guided plane has been reduced from 1.53 ±0.04 in an uncoated region of the waveguide to 1.17 ±0.01 in the Au coated region using optimum pump launch conditions.
