Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 108 words
A rotational-vibrational laser system comprising: means containing molecular hydrogen of a species selected from the group consisting of H2, D2, HD, HT, and DT at a pressure of about 10 atmospheres, means for maintaining said molecular hydrogen at a temperature of about 77*K, means for subjecting said molecular hydrogen to at least one beam of electrons of an energy between about 1 and 5 eV, and means associated with said containing means defining an optically resonant cavity, whereby activation of said molecular hydrogen by said electrons creates a population inversion in the hydrogen and consequent oscillation on rotational vibrational energy levels producing high intensity and high energy output.
