摘要
The vaporization threshold was measured under the irradiation of 1.064-μm, 10-ns pulsed laser. Then we calculated the vaporization temperature based on the conservation law of energy and analyzed the vaporization time based on our established model. These results coincided well with the information from the micrograph of scanning electron microscope （SEM） and the spectra of the plasma. Besides, the laser ablation rate was also computed and discussed theoretically.
