Two models of femtosccond laser-stimulated desorption (LSD) are considered. One is the LSD due to a coherent "giant" optical mode vibration created by a femtosecond laser pulse and the other is the predesorption induced by a femtosecond UVvisible laser.
## Abstract The multiple photon absorption and decomposition of ethanol irradiated by pulsed 9P18 infrared radiation (1048.7 cm^β1^) from a TEA CO~2~ laser has been studied in the fluence range 15 to 5 J cm^β2^. The absorption crossβsection is pressureβdependent due to rapid collisional rotational
