A strong Q-switched N20 laser capable of60 MHz frequency sweep is used to induce population inversiou by optical adiabatic rapid passage on the +[asQ(8,7)] transition of I4 NH3. The fa'st inversion and the subsequent return to equihbrium are detected by a cw weak counterpropagating N20 laser, and ar
