Abstract

The laser ablation of quartz, fused silica and natural silicates induced by pulsed CO₂ laser irradiation has been studied. The frame image of laser induced plume by use of high speed photography method with 2 microsecond expose of each frame has been made. It has been observed the formation of two different type of laser plume during laser pulse action. The first type plume connects with the selective ablation of Si_mO_n complexes whereas second type plume connects with the thermal heating caused by dissipation of laser energy in to system of low frequency acoustics phonons.
