  • Abstract
    We report divergence, astigmatism and M2 measurements for 8.77 mum quantum cascade lasers. Measurements showed divergence of 62deg by 32deg FWHM plusmn 2deg and M2 values of 1.81 and 1.22 for the fast and slow axes respectively. Astigmatism at source was ~4 mum, less than half a wave.
