Abstract
An experimental investigation of laser-induced breakdown using Nd:YAG laser harmonics for argon, nitrogen and oxygen gases is reported. Pres sure dependence as well as wavelength dependence of the breakdown thre shold irradiance I-th is investigated. The experimental observations f or 1.064 and 0.532 mu m laser wavelengths are in agreement with theore tical calculations which include the effects of multiphoton ionization and cascade ionization.
