【 摘 要 】

Ablation of BaWO₄ Raman crystals with different impurity concentrations by ultrashort laser pulses was experimentally studied. Laser pulses with duration varying from 0.3 ps to 1.6 ps at wavelengths of 515 nm and 1030 nm were applied. A single-pulse optical damage threshold of the crystal surface changed from 1.3 J/cm² to 4.2 J/cm² depending on the laser pulse parameters and BaWO₄ crystal purity. The optical damage threshold under multi-pulse irradiation was an order of magnitude less.
