Optimization of a self-terminating ionized strontium laser in a pulsed periodic mode
Abstract
Experiments have been carried out to determine the optimum operating conditions in a pulsed periodic mode for a self-terminating ionized strontium laser generating at 1.03 micron. It is found that in this operating mode, the lasing power is determined by the power input of the discharge and by the degree of radial inhomogeneity of strontium atoms and ions. In order to obtain maximum mean lasing power, it is essential that the strontium vapor pressure be maintained at its maximum, in addition to the known requirements on the excitation parameters for self-terminating lasers. The pulse repetition rate should be sufficiently high to permit the use of residual ionization of strontium atoms in the periods between pulses; however, the pulse repetition rate must not exceed the relaxation frequency of the gas temperature in the active volume.
