Pulsed Laser Heating

Pulsed laser heating is used to label aerosols or absorbing vapors in a flow. In an absorbing vapor, the photothermal heating creates a travelling thermal lens that can be detected by a probe-beam deflection scheme yielding information on flow velocity and the concentration of absorbing species. The absorption by volatile aerosols is detected by transient variation in Mie scattering caused by particle evaporation. In addition, the velocity of a single moving aerosol can be measured by monitoring its infrared thermal emission induced by an excitation laser beam.

Pulsed Laser Heating

Abstract A simplified finite element model is built to study the thermal response of the 193-nm pulsed-laser calorimeter. The nonequivalence between pulsed-laser heating and electrical heating is estimated to be 0.46% at the thermocouple locations by comparing the calibration factors for average-power laser heating and electrical heating. This study should help the development of calibration and measurement standards in pulsed energy measurements for deep ultraviolet excimer lasers that are important for photolithographic and materials processing applications.
