| 摘 要： | 报道了多种商用光学玻璃和激光玻璃在800nm,120fs,1kHz脉冲激光作用下,产生光致暗化的阈值.并对照射前后的玻璃进行ESR分析,结果表明,光致暗化是由于玻璃内生成空穴捕获型色心的结果.认为玻璃在800nm飞秒激光照射后所产生的色心来源于玻璃的多光子吸收

| Abstract: | The thresholds of laser-induced darkening in different optical and laser glasses irradiated by a 800nm, 120fs, 1kHz Ti:sapphire laser are reported for the first time. The ESR spectra of irradiated glass show laser-induced darkening results from color-center generation. The glasses are transparent in the wavelength of 800nm, so we suggest that color-center is generated through multi-photon absorption. |
