When the strong Doppler limit is applicable, a tuned laser containing Doppler-broadened gain and absorption media may produce a steady-state standing-wave field that is both frequency pushed and isolated from the branch of on-resonance steady states. The locus of the isolated states plotted as a function of the linear gain is a pair of closed loops, called isolas. Similar running-wave modes are not found in this limit. A connection is indicated between the isolated steady states and both the mode-pushed states discovered by Bennett [ The Physics of Gas Lasers ( Gordon and Breach, New York, 1977)] and the instability found by Casperson [ Phys. Rev. A 21, 911 ( 1980)].
