Summary form only given. We obtain the highest peak power yet reported among any mid-IR semiconductor diode lasers at emission wavelengths beyond 3 /spl mu/m. Note also that the power values reported here have been corrected only for the transmission coefficients of the collection optics and not corrected for beam divergence. If the spatial divergence of the laser beam is taken into account, the actual emitted powers and differential external quantum efficiency (DEQE) would be considerably higher.
