Is it possible to use a bulk medium active element in a optic fiber resonator as a active part of laser ? Any suggested publications ? Thanks!
It is absolutely possible. But what advantages can you get using this combination ?
Such combinations, as I remember, were used long time ago, before the development of active fibers with high performance, for example, for modeling of resonators with big length. At present time, when you can easily include fiber amplifier into fiber resonator, no sense to combine bulk amplifier with passive fiber components. For example, is not possible to increase pulse energy, because it will be restricted by laser damage threshold of the fiber.
It was only idea how to make a pulsing with bulk amplifier (new medium with interesting amplification range about 2mkm). I suggest to use a nonlinear polarization evolution to mode lock it. Fiber is supposed to be a nonlinear element in this scheme. But I think may be a sesam using is a more suitable for us. Thanks !
