摘　　要：医用激光产品对人体,特别是对人眼的危害差异性,主要取决于激光束的波长、能量以及脉冲特性等因素,激光的辐射水平即为衡量激光危害的重要指标之一。GB 7247.1-2012《激光产品的安全第1部分:设备分类、要求》对激光产品按辐射水平进行了分类,为确定激光分类标准规定了两种评估方法,即默认(简单的)评估和扩展光源评估。The difference of the hazards of medical laser products to human body,especially to human eyes,mainly depends on the wavelength,energy and pulse characteristics of laser beam.The radiation level of laser is an important index to measure the harm of laser.Laser products are classified according to radiation level in GB 7247.1-2012 Safety of Laser Products-Part 1:Equipment Classification and Requirements.Two evaluation methods,the default(simple)evaluation and the extended light source evaluation are prescribed in the standard for determining the laser classification.
