Laser using I*Xe exciplexes

Lasing was observed in iodine atoms perturbed by xenon at pressures up to 30 atm. A reduction in the delay of the laser pulse relative to the beginning of the pump pulse with increasing xenon pressure confirmed that there is a broad strong IXe(1/2)'→(1/2)'' exciplex transition and opened up the possibility of generating picosecond laser pulses at ~ 1.3 μm.
