Description
Summary:Using a short-risetime traveling-wave discharge system, lasing has been produced in molecular hydrogen in the 1600-Å region and confirmed by direct observation of extensive amplification in the direction of travel. Pulsewidths and powers on the order of 1 nsec and hundreds of kilowatts, respectively, are observed. The ten H2 lines resolved extend from 1567 to 1613 Å in the Lyman band. The laser lines originate from transitions between the vibrational levels of the state B(2pσ1Σu+) and the higher vibrational levels of the ground state X(1s1Σg+).
