Abstract:
A method is proposed for attaining pulsed laser emission at the wavelength of 1.3 μ from iodine atoms as a result of electron-beam-controlled excitation of hydrogen–iodine mixtures. Quasiresonant vibrational–electronic exchange between H2 and I results in a population inversion. It is shown that a deposited energy of the order of 0.3 J·cm–3·amagat–1 corresponds to an ultimate laser efficiency of ~50%.
