Threshold measurements of a non-resonant continuous wave Raman laser in H/sub 2/

摘要: Summary form only given. High finesse cavities have recently been used to produce an optically pumped, non-resonant cw Raman laser at 683 nm (Stokes) with a threshold of less than 5 mW pump power. However, these measurements were limited rates greater 4 times threshold. We report data for output power and photon conversion efficiency as functions near compared theory previously developed similar system. A measurement 3.2/spl plusmn/0.4 optical high 40% are demonstrated.
