THE HEATING OF METAL AND DIELECTRIC SAMPLES BY PULSED-LASER RADIATION

A thermocouple-based calorimetric technique is described for studying in-vacuum samples that are exposed to single laser pulses generated in the free-running mode. The degree of heating the samples, the heat fl uxes, and the fraction of the laser-pulse energy converted into residu al thermal energy of the samples were determined at laser radiation in tensities of 10(5) - 10(7) W/cm2. Approximating expressions are obtain ed for computing the sample heating and the effect of initial temperat ure on the enthalpy increment.
