Abstract
Linear birefringence is a polarization property of materials that results in a phase shift between orthogonal polarizations. Birefringence has been used to monitor collagenous tissue structures as a function of thermally-induced denaturation. Studies performed over long heating times have shown that both rat tail tendon (RTT) and cornea lose their birefringence as the heat applied causes a loss in the sample's structure. This paper reports the birefringent response of RTT to rapid heating by 200-μs-long, 2.1-μm Ho:YAG laser pulses. The results indicate that dynamic measurement of linear birefringence can be used as an optical feedback parameter to control laser tissue heating.
