Abstract

Summary form only given. Experimental and theoretical results of nonlinear transmission measurements on single crystals of the polybis(p-toluene sulfonate) ester of 2,4-hexadyne-1,6-diol (pTS) are reported. The optothermal properties of the above material have been determined from the temperature dependence of the linear transmission spectrum. A value on the order of -1 × 10-2 for dn/dT is estimated. This value of dn/dT is some 50 times larger than that of the semiconductor ZnSe, which is currently used in optically bistable plates for optical circuitry. To verify this large dn/dT, both pulsed energy transmission measurements and CW thermal defocusing experiments have been carried out. In the defocusing experiments, for power levels as low as 3 mW, the far-field beam profiles differ from those observed using inorganic semiconductor mateiral in that the incident Gaussian breaks up into two distinct spots. This is attributed to the anisotropic heat conduction in pTS.
