J. Franzke et al., Tunable UV generation at 283 nm by frequency doubling and sum frequency mixing of two semiconductor lasers for the detection of Pb, SPECT ACT B, 53(14), 1998, pp. 1951-1955
High resolution atomic absorption measurements of lead at 283 nm in a vapor
cell were performed by frequency doubling an 850 nm laser diode to obtain
425 nm light, followed by sum frequency generation of the harmonic radiatio
n with a second 850 nm laser diode. (C) 1998 Elsevier Science B.V. All righ
