Q-switched iodine laser emitting at two frequencies

An investigation was made of the characteristics of stimulated emission of short light pulses in a transverse magnetic field. Conditions for simultaneous emission at two frequencies corresponding to the F' = 3→F = 4 and F' = 2→F = 2 transitions. In magnetic fields of 0–800 Oe intensity the frequencies of the σ Zeeman components of the above 3–4 and 2–2 transitions coincided with the central frequencies of the corresponding transitions in the luminescence spectrum of atomic iodine in the absence of a magnetic field.
