We report the observation of midinfrared super radiant pulses emitted from molecular gases pumped by a narrow-band, continuously tunable infrared optical parametric oscillator. Molecules pumped either into a vibrational combination band or a vibrational overtone state decay by means of super radiant emission to a lower vibrationally excited state. Emission was observed in N{sub 2}O at 4.5 and 8 {mu}m, and in C{sub 2}H{sub 2} at 13.6 {mu}m and 15.7 {mu}m. Pulse energies as high as 0.5 mJ and pulse widths as short as 7 ns make this an excellent technique for the production of intense midinfrared light. {copyright} {ital 1997 American Institute of Physics.}
