| 英文摘要 | The laser damage characteristics of calcium fluoride (CaF2) crystals with various lattice planes irradiated by 355-nm pulse laser are investigated. Further, the damage thresholds and damage morphologies of three different lattice planes, i.e., (100), (110), and (111), are measured under a 7.8-ns pulse laser irradiation. In addition, the photothermal absorption is evaluated by using the surface thermal lensing technique. The (111) CaF2 crystal exhibits the highest photothermal absorption and lowest laser damage threshold. The (111) damage morphology comprises a melt pit, which is accompanied by lamellar peeling, indicating that this plane is easily cleaved by the 355-nm laser. The (100) and (110) damage morphologies also comprise a melt pit; however, the damage threshold and photothermal absorption have no clear correlation with the two lattice planes. 2019, Chinese Lasers Press.
