Abstract :
Room-temperature CW laser emission at 2.1μm is reported for the first time with both multimode diode arrays and single-stripe diode pumping. CW room-temperature slope efficiencies of 17% and 16% were obtained using a 100 mW multimode diode array and a 30 mW single-stripe diode, respectively. To date, CW outputs of several milliwatts at 2.1μm have been obtained.
