Multistable generation of monochromatic radiation in solid-state lasers

It is shown that a solid-state laser with unpumped sections of action medium which act as a saturable absorber, may operate in a stable, single-mode cw lasing regime. The establishment of lasing in a particular mode under steady-state conditions depends on the initial conditions of transient evolution. Pis’ma Zh. Tekh. Fiz. 24, 89–92 (February 26, 1998)
