碘激光的H2振动受激拉曼阈值研究
Vibrational stimulated Raman conversion threshold of H2 pumped by iodine laser
摘要
Abstract
The hydrogen vibrational stimulated Raman scattering (SRS) pumped by a photolytic iodine laser (PIL) has been demonstrated for the first time.Under the condition of PIL pulse energy of 100-130 mJ (100 ns), double pass configuration is applied to reduce the SRS threshold successfully.SRS laser of 2900 nm is obtained and the photon conversion efficiency reaches 8.7％.The conversion efficiency of the first stokes light is found not affected by the pressure of hydrogen, once it is more than 1 MPa.Theoretical analysis is applied to explain this phenomenon.关键词
