FIBER LASERS

摘要

Fiber lasers use structures that confine the optical radiation in the spatial coordinates that are transverse to the direction of propagation of the laser radiation. By confining the optical field in this manner, the effects of diffraction can be countered and long lengths of laser material can be used. Use of long lengths of laser material can generate high laser gains and efficient laser operation. The physics of both continuous and Q-switched fiber lasers are investigated.
