Abstract
The operation of a low‐field spin‐flip Raman (SFR) laser utilizing a closed‐cycle refrigerator is reported. SFR laser conversion efficiencies as high as 80% have been observed enabling us to observe the operation of a IV Stokes SFR laser for the first time. SFR gain in InSb is measured that gives a spontaneous SFR linewidth as narrow as ∼ 400 MHz.Keywords
