Gain of the active medium of an iodine photodissociation laser in a magnetic field
The influence of a magnetic field on the gain of the active medium of a photodissociation laser oscillator (amplifier) operating under various conditions is studied theoretically allowing for the hyperfine structure of the active transition in the iodine atom. It is shown that an inhomogeneous longitudinal magnetic field always ensures a practically monotonic reduction in the gain and provides the optimal means for magneticfield control of the gain.
