钕玻璃固体激光器,已应用于钟表工业的红宝石钻孔工艺。这类激光器产生波长1.06μ的红外辐射,脉冲频率2～8赫,脉冲能量0.1～0.3焦耳,脉冲持续时间150～250微秒。作者于1973～1975年,对钟表工业红宝石钻孔车间,进行全面劳动卫生和工人健康调查。对象为108名(男性57%)20～40岁调试、操纵激光器工人,接触工令低于3年者占80%,其余不超过3.5～4.5年,对照组47人。主要为钳工、检验员、自动化机器调试人员等),二组年令、性别组成,基本相符。[劳动卫生调查] 工人劳动中,受激光的散射和漫反射作用,能量密度距激光斑10～30 cm工作点,为3×10~(-5)～6×10~(-6)焦耳/cm~2。
Neodymium glass solid-state lasers have been used in the ruby drilling process in the watch industry. Such lasers generate infrared radiation with a wavelength of 1.06μ, with a pulse frequency of 2 to 8 Hz, a pulse energy of 0.1 to 0.3 Joule and a pulse duration of 150 to 250 microseconds. The author from 1973 to 1975, the watch industry ruby drilling workshop, a comprehensive survey of labor and health workers. Subjects were 108 (57% male) workers aged 20-40 who were commissioned and maneuvered to work with laser workers. 80% of workers were exposed to work less than 3 years, and the remaining no more than 3.5 to 4.5 years and 47 were control subjects. Mainly fitter, inspector, automated machine debugging personnel, etc.), two sets of seasonal, gender composition, the basic match. [Labor Health Survey] The work of workers is affected by laser scattering and diffuse reflection. The energy density ranges from 10 to 30 cm from the laser spot to 3 × 10 -5 to 6 × 10 -6 J / cm ~ 2.
