【摘要】 激光器在光电信息类实验课程中已得到广泛的应用，如何在实验过程中提高激光防护意识并落实必要的防护措施，实现激光的安全使用，这是高校实验室使用激光不容忽视的问题。根据激光产品的危险级别分类，详细描述了不同波长及入射角的激光辐射对眼睛造成的不同伤害，以及激光辐射对皮肤危害涉及的几个因素。探讨了高校实验室激光安全防护的方法，包括激光警告标志等的规范制作和布置，激光安全防护用具的选择，特别是激光防护镜的选择与使用。更多还原

【Abstract】 Laser has been widely used in the course of photoelectric information. How to improve the laser protection awareness and implement the necessary protective measures in the process of experiment to realize the safe use of laser is a problem that can not be ignored in the use of laser in university laboratory. According to the risk classification of laser products, this paper describes in detail the different damage to eyes caused by laser radiation of different wavelengths and incident angles, as well as several factors related to the harm of laser radiation to skin. This paper discusses the methods of laser safety protection in university laboratories, including the standard production and arrangement of laser radiation warning mark and instruction mark, the selection of laser safety protection equipment, especially the selection and use of laser protective glasses.更多还原
