Continuously tunable and coherent radiation has been obtained in the ranges of 66.5-300 μm and 72.7-237 μm for two configurations of phase-matched difference-frequency generation, respectively, in zinc germanium phosphide. The highest output peak powers are measured to be 36 and 19 W for the two configurations, respectively.
