Order-of-magnitude increases in output power and efficiency have been obtained from optically pumped FIR lasers using a new FIR waveguide laser geometry and a new output coupler. Conversion efficiencies 5--15% of the theoretical maximum are reported for several lines between 71 and 1222 ..mu..m and cw output of 400 mW at 118 ..mu..m and 40 mW at 496 ..mu..m are obtained from a laser 2 m in length. These results indicate that the stronger FIR transitions are capable of cw operation at the 0.1--1.0-W level for 100 W of CO/sub 2/ pump power. (AIP)
