Stimulated rotational Raman scattering (SRRS) at multiwavelength pumped by TEA CO 2 laser was demonstrated in this paper. Raman mediums were cooled by liquid-N 2 and a multiple-pass cell (MPC) with 25 passes was designed and used. When the para-H2 was pumped by single-longitudinal-mode (...

We report on the generation of pure rotational stimulated Raman scattering in a hydrogen gas hollow-core photonic crystal fiber. Using the special properties of this low-loss fiber, the normally dominant vibrational stimulated Raman scattering is suppressed, permitting pure conversion to the rotational ...
A quantum-statistical treatment of stimulated Raman scattering in a gaseous system is presented using a density-matrix formalism. The molecular (atomic) system is described by three energy levels. Both atomic system and the radiation fields are quantized. The effects of atomic motion and detuning ar...
Stimulated rotational Raman scattering from para-H(2) pumped by a CO(2) TEA laser. We have observed stimulated rotational Raman scattering (SRRS) from para-H(2) pumped by a CO(2) TEA laser operating on the strong P- and R-branch transitio... P,Rabinowitz,A,... - 《Optics Letters》...
Many of the H2O lines are pure rotational lines, and their line-widths exhibit the expected general narrowing trend as the rotational quantum number increases. 38 被引用 · 0 笔记 引用 The external-resonator cw spin-flip Raman laser; output characteristics and spectroscopic applications R.B. ...
