A new mid-infrared laser in hydrogen which produces an output when excited by a high voltage pulse discharge in a long, low loss cavity to produce laser action in three or more lines as output pulses with lengths varying from less than 1 microsecond to over 6 microseconds with wavelengths in the 3 .mu.m band including 3.71 .mu.m, 3.77 .mu.m, and 3.84 .mu.m.

Mid-infrared laser in molecular hydrogen

A cryogenic infrared laser in deuterium in which an output is produced by exciting the deuterium after it has been cooled to cryogenic temperature with a high voltage pulse discharge to produce laser action in three or more lines as output pulses with varying lengths and with wavelengths in the 4 .mu.m band and including 4.52 .mu.m, 4.60 .mu.m, and 4.71 .mu.m.
