A maximum absorption cross-section of 1.7 × 10-20 cm2 with spectral bandwidth of 2.4 nm centered at 970.5 nm and a maximum emission cross-section of 6.5 × 10- 20 cm2 with spectral bandwidth of 4.6 nm centered at 1024 nm were determined at 120 K. Cryogenic continuous wave laser operation was achieved using a VBG stabilized laser diode emitting around 969 nm as pump source. At 120 K, a maximum output power of 17.50 W was achieved around 1024 nm corresponding to a slope efficiency of 87% with respect to the absorbed power.
