摘要

The measured optical density of various laser eye protection samples is presented as a function of irradiance using femtosecond laser pulses. We show that the protective quality of some eyewear degrades as irradiance increases. In previous studies this problem has been demonstrated for samples irradiated by nanosecond pulses, but the current study shows that some modern laser eye protection seems to be robust except for the irradiance level possible with ultrashort laser pulse exposure. We discuss the most likely saturation mechanisms in this pulse duration regime and its relevance to laser safety.
