摘要：
We report experimental investigation on photoacoustic emission from air plasma created as a result of interaction of a focused 50 fs intense laser-pulse in air. Emphasis is to study the dependence of acoustic emissions on laser energy, radial distance and laser polarization direction. Experimental results indicate quadratic dependence on laser energy, reciprocal dependence on radial distance and independence on laser polarization direction of photoacoustic emissions from strong femtosecond-laser-induced air plasma.
