Kurzfassung:
The bulk laser-induced damage threshold (LIDT) of a strontium tetraborate (SrB 4 O 7 , SBO) single crystal has been measured for the first time. Single-shot and multi-shot tests are carried out using a 266 nm deep ultraviolet (DUV) laser. Under single-shot irradiation, the bulk LIDT of SBO crystal is 1.5 times higher than that of synthetic silica glass. On the other hand, under multi-shot irradiation, the bulk LIDT of SBO is also higher than synthetic silica glass regardless of the number of shots. When the number of shots increased from 10 2 to 10 4 , SBO crystal’s bulk LIDT has only decreased by less than 11% compared to 44% of synthetic silica glass. Although the damage mechanism of SBO crystal under multi-shot irradiation is considered to be due to material modification fatigue, SBO single crystals are found to be excellent optical materials that exhibit bulk laser-induced damage resistance in the DUV region.
