MODE-LOCKED PULSE GENERATION IN PASSIVELY SWITCHED LASERS

Abstract

The behavior of a passively switched laser is described by a set of partial differential equations, which are integrated numerically. For short upper-state lifetimes of the absorbing medium, the calculated output of the laser is a train of narrow pulses. Pulses occur either singly or in multiples during the roundtrip time 2L/c, depending on whether the absorber is near one mirror or at an intermediate position.
