Paper Abstract

In 1967, Herzberg predicted the existence of the hydrogen triplet series lasers and noted that the far infrared laser ((Delta) V equals 0) transitions should produce very strong laser action. A laser in the hydrogen triplet spectrum was discovered and reported by Barr and McKnight in 1982. Dabrowski and Herzberg confirmed the spectroscopic assignments of the laser lines, and restated that there should be a strong laser on the triplet transitions. The experimental work was strictly oriented to discovering the existence of these lasers. Thus the deductions we make concerning power capability are limited by the type of data available. The experiments show that: (1) the laser is on the triplet series lines as stated above, (2) the three lines start emission within a fraction of a microsecond of one another and terminate at approximately the same time, and (3) the lines seem to be self terminating.
