在液氮温度下氢气中诱导激发拉曼散射所产生的辐射可作为测定As、Se、Te和Zn诸元素的原子荧光可调激光激发紫外锐光源,这些元素的共振激发态通常高出基态40000cm~(-1)。为了增加激发态,要求初级辐射的波长短于由倍频激光技术提供的波长,这些波长是在诱导激光拉曼散射可调染料激光辐射所能达到的波长范围内。在上述研究中,YAG脉冲染料激光光源提供初级辐射,
Radiation generated by induced Raman scattering in hydrogen at liquid nitrogen temperature can be used as an atomic fluorescence tunable laser excitation UV source for the determination of As, Se, Te and Zn, and the resonance excited states of these elements are usually higher than the ground state of 40000 cm ~ (-1). In order to increase the excited state, the primary radiation is required to be shorter in wavelength than the wavelength provided by the frequency doubling laser technology, within the wavelength range that can be achieved by the induced laser Raman scattering tunable laser radiation. In the above studies, YAG pulsed dye laser sources provide primary radiation,
