A fiber laser is a type of laser in which the active gain medium is an optical fiber doped with rare-earth ions such as erbium, ytterbium, or neodymium. Fiber lasers generate coherent light through the process of stimulated emission, where photons...

The figure of merit of a resonator, defined as (2p) x (average energy stored in the resonator)/(energy dissipated per...

A gas laser in which the electrodes are mounted perpendicular to the optical resonator.

In a laser, the optical resonator formed by two coaxial mirrors, one totally and one partially reflective, positioned so...
