Abstract

Under excitation of 355nm or 266nm UV radiation some strong emissions have been observed in PbI 2 vapor. Analysis shows that they are 1st, 2nd order Stokes and 1st anti-Stokes components of 355nm laser and 1st order Stokes and anti-Stokes components of 266nm laser. The initial states of Raman transition are 6p 2 3 P 1 and 6p 2 3 P 2 metastable states of atomic Pb, respectively. The population on it is created by photodissociation of PbI 2 . The dependences of Raman components on pump power, PbI 2 density and pressure of buffer gas are investigated experimentally.

Anti-Stokes Raman Lasers

J. C. White, D. Henderson

This paper reports what we believe to be the first observations of stimulated, anti-Stokes Raman laser emission. A metastable Tl*(6p 2po3/2) population inversion was created by selective photodissociation of TlCl, and Raman scattering using 532 nm and 355 nm pump lasers resulted in stimulated emission at 376 nm and 278 nm, respectively. Likewise, inverted I*(5p5 2Po1/2) atoms have been used as a Raman medium; and with a 206 nm pumping source, we have generated tunable VUV radiation at 178 nm.

STIMULATED RAMAN-SCATTERING AND RESONANT LASER-RADIATION IN PHOTODISSOCIATED LEAD ATOMS

J Zhang, By Cheng, Dz Zhang +3 more

Strong stimulated radiation at wavelengths 3740 A was observed when PbCl 2 molecules were photodissociated by a 2660 A UV laser. Based on spectral characteristics and Pb energy level structure, this radiation was judged to be resonant laser radiation and stimulated Raman scattering due to the populated 6p 2 3 P 2 metastable Pb atoms from photodissociated PbCl 2 molecules. A theoretical model was developed to describe the whole process, and experimentally fitted to determine the photodissociation coefficient of the metastable Pb atoms from dissociated PbCl 2 by 2660 A laser

Stimulated Raman scattering and resonant laser radiation in photodissociated Pb

J Zhang

Strong stimulated radiations at wavelengths 3740 A have been observed when PbCl2 molecules are photodissociated by 2660 A ultraviolet laser. Dependences of these radiations on the pump laser intensity and PbCl2 molecular density have been studied experimentally. A theoretical model to describe these processes is put forward. These two raditions are identified as resonant laser radiation and stimulated Raman scattering originated from bhe population of the metastable level 6p23P2 of atomic Pb, which is produced by two-photon dissociation of PbCl2. When molecular density of PbCl3 is 6.21×1016cm-3, the maximum populations on the two metastable levels, 6p23 P2 and 6p21D2, of atomic Pb are almost same, which equals 2.0×1016cm-3.

Anti-Stokes Raman laser

J. C. White, Don O. Henderson

The first observation of nonresonant, stimulated anti-Stokes Raman emission is reported. A metastable $\mathrm{Tl}(6p^{2}P_{\frac{3}{2}}^{o})$ inversion is created by selective photodissociation of TlCl. Raman scattering from the Tl metastable state to ground using 532- and 355-nm pump lasers resulted in stimulated emission at 376 and 278 nm, respectively. Conversion efficiencies up to 10% are reported.

Competition between stimulated Raman scattering and resonant laser emission

Cheng Bingying, Zhang Jie, Zhang Daozhong +3 more

Competitive phenomena between stimulated Raman scattering and resonant laser emission in atomic lead are studied through photodissociation of PbCl 2 with a UV laser. The different dependences of their intensities on the UV power, the density of PbCl 2 and the pressure of buffer gases are investigated. The results indicate that under the conditions of high pump intensity and low buffer gas pressure SRS can have the advantage of RLE.

Anti‐Stokes Raman lasers

J. C. White, Don O. Henderson

The first observations of UV and VUV anti‐Stokes Raman laser emission are reported. Anti‐Stokes Raman scattering of 532 nm and 355 nm pump lasers using inversted metastable T1 atoms resulted in stimulated emission at 376 nm and 278 nm respectively. Also, a tunable 178 nm anti‐Stokes laser using metastable I atoms has been constructed.
