Thermal Analysis of Multiphoton Absorption at 193 nm in Volume-Absorbing Glass
Keyword(s):
Two-photon absorption in volume-absorbing materials may be significant for high-power, short-pulse excimer laser irradiation. In the present work, the effects of two-photon absorption on the laser intensity propagation and the penetration depth are investigated. The temperature history of a glass plate during pulsed ultraviolet (UV) laser heating is predicted. The results show that the two-photon absorption can compress the volume-absorbing effect to surface absorption and increase the peak temperature on the glass surface. This will reduce the damage threshold, increase the energy loss, and reduce the accuracy of pulsed-laser calorimeters.
