From: Thermal-stress-induced birefringence management of complex laser systems by means of polarimetry

Thermally induced birefringence measured in the laser system which includes also several beam rotations, image-relays and other non-polarization effects. LB Phase Delay the phase delay of the linear birefringence, LB Axis Angle azimuth of the birefringence axis, CB Phase Delay circular birefringence-driven polarization rotation angle.
