We have measured the free-carrier recombination time in polycrystalline bulk ZnSe to be in the range 7-14 ns at room temperature. We used an excite and probe technique with near-band-edge nanosecond laser pulses to measure the decay of induced free-carrier absorption. We estimate the free-carrier-pair absorption cross section to be in the range (3-6)×10-17 cm 2.
