Abstract

Abstract: The bias-pumped gain-switched fiber laser proposed by us is considered to be a novel pulsed fiber laser based on a new pulsing mechanism. With a certain signal power seeding, synchronization of the temporal evolution can be maintained between the output signal laser and the pump. The seed laser can conveniently be supplied with power by a CW pump; this is called bias-pump power. A pulsed pump is responsible for shaping the output pulse. Stable pulsed lasers with a tunable duration can be achieved under a bias pump combined with a pulsed pump. In addition, the temporal shape of the output pulses can be controlled based on this new pulsing mechanism. Compared with conventional gain-switched fiber lasers, a much simpler pulsed laser design can be provided by this novel pulsed fiber laser because there is no need to add a control unit to realize fast gain-switching.
