Characteristics of the laser emission spectrum of a thallium photodissociation laser
The results are reported of investigations into the spectral and energy characteristics of a thallium photodissociation laser, emitting due to the 7S/sub 1/2/--6P/sub 3/2/ (lambda = 535 nm) and 7S/sub 1/2/--6P/sub 1/2/ (lambda = 337.6 nm) transitions. The experiments were performed using two types of resonator, and this made it possible to increase the radiation power density above the superradiance level and to operate in two-wavelength lasing regimes. On reaching a certain power density the structure of the laser emission spectrum changed, the nature of this change being different for the different lines. A discussion of the results obtained is given.
