Fiber lasers technology oers unique advantages over conventional bulk laser technology. For example all-normal dispersion ber cavities can be build more compact, thus more environmental stable and cheaper, and are therefore very attractive for industrial products.
The goal of this work is to build and operate a monolithic integrated all-normal dispersion femtosecond ber oscillator using an all-ber remote electronically adjustable polarization controller. For this purpose a suitable polarization controller was selected and incorporated into a ber laser cavity. The ber laser cavity was designed to operate at all-normal dispersion and therefore does not need any kind of dispersion control or dispersion compensation inside the cavity. In such a conguration the output pulses are highly chirped pulses with picoseconds duration that can be dechirped externally down to the femtosecond regime. For many applications the output energy of modelocked ber lasers is too low and needs to be amplied. To keep nonlinearities low, thereby preserving pulse quality, the concept of chirped pules amplication is very attractive.
