英文摘要	An interferometric based diagnostic for experimentally determining the time-dependent OPD change in an optically heated media works by heating a glass window with a CO2 laser, effectively simulating high power end-pumping in a rod. Temporal OPD changes are measured by automated counting of interference fringes as they are generated by the thermal effects, and a two-dimensional, time-dependent model is developed to describe the radial temperature distribution in a cylinder, the stress and strain distributions, the thermal expansion, and the associated OPD change caused by a Gaussian heat source.
