A continuous wave (CW) power of 11 W with a power conversion efficiency of 23% has been demonstrated for a 1 cm wide array at 10°C heatsink temperature. The array operates at a CW optical power of up to 5.6 W at 40°C without thermal rolling. T0 for the array is 59.5 K. 100 W optical power (1 ms, 25% duty) was achieved for a 2D array. The lasing wavelength is 1.87 µm at 100 W.
