Abstract

Self‐focusing of ruby laser light is studied as a function of sample length and temperature in the isotropic phase of nematic liquid‐crystal MBBA. The critical power for self‐focusing, 0.36 kW, observed near the phase transition temperature is a factor of 20 times less than that for CS₂. The corresponding nonlinear index 4.4 × 10⁻¹⁰ esu is the largest value known so far for any material.
