The external-resonator cw spin-flip Raman laser; output characteristics and spectroscopic applications

Critique of tunable infrared lasers

“…Such mode-hops leave gaps in the coverage of typically 20-70 %. The low-temperature lasers have been operated in external cavities to eliminate the mode-hops at the expense of simplicity and convenience (Mozolowski et al 1979). The output power of the tunable i.r.…”
