We report a new design for a polarization-selective laser cavity
with birefringent diffractive phase elements. This laser cavity can
create two modes with different polarizations and profiles launched
separately from two end mirrors. The numerical simulation results
show that the constructed laser cavity can successfully generate two
orthogonal polarization modes with a uniform circular shaped pattern
output from one end mirror and a uniform square-shaped pattern output
from another end mirror.
