Abstract

The time dependence of the thermal lens effect in solids is analyzed above modest power densities (ca. 1 W/cm2). Oscillatory behavior is observed. Excellent agreement between theory and experiment is shown for oscillations as functions of both laser power and temperature. The theory also describes previously unexplained results in thermochromic liquids (M. V. Vasnetsov, JETP Lett., 50, 480 (1990)).
