Abstract
The thermal effects induced by pulsed laser absorption in an optical medium were simulated. In particular, the dependences of maximum temperature increase and decay time constant on the laser beam diameter and the medium absorption coefficient were investigated. The maximum temperature increase showed the inverse square dependence on the laser beam diameter, and the decay time constant was found to be almost independent of the laser beam diameter for relatively large absorption coefficients. As the absorption coefficient increased, the maximum temperature increase increased and the decay time constant decreased. The maximum temperature increase was directly proportional to the absorption coefficient, and the decay time constant was found to be almost independent of the absorption coefficient for relatively small laser beam diameters.
