Leong, M B

Stimulated Raman scattering (SRS) in hydrogen (H2) at liquid nitrogen (Na2) temperatures has been evaluated as a tunable, sharp-line ultraviolet laser source for the excitation of atomic fluorescence of those elements, such as As, Se, Te, and Zn, whose resonance excited states are usually more than 40,000 cm above the ground state. To populate these states requires primary radiation of such a short wavelength to not be accessible by conventional, laser-frequency doubling techniques. A Nd:YAG pumped dye laser provided the primary radiation that was scattered in the SRS cell into Stokes and anti-Stokes components. Data on the analytical figures of merit are presented and compared with those obtained by conventional inductively coupled plasma-atomic emission and hollow cathode excited atomic fluorescence. 53 refs., 14 figs., 8 tabs.
