Optical emission studies are carried out on the plasma generated by nanosecond radiation of the 532 and 1064 nm lasers on KTiOAsO{sub 4} (KTA) samples with the intensity of 10{sup 8}-10{sup 9} GW/cm{sup 2}. Our studies indicate that the amount of evaporated matter in plasma evolution depends on the laser wavelength. The dimension of the self-regulating region shows a clear laser-intensity dependence, which increases from 3 mm at 0.22 GW/cm{sup 2} to 8.5 mm at 1.72 GW/cm{sup 2}. This work is expected be helpful for optimizing the experimental parameters of growing KTA thin films using pulsed laser deposition.
