Zusammenfassung (Englisch)

error: u'Fiber lasers technology o\x0bers 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 \x0cber oscillator using an all-\x0cber remote electronically adjustable polarization controller. For this purpose a suitable polarization controller was selected and incorporated into a \x0cber laser cavity. The \x0cber 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 con\x0cguration 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 \x0cber lasers is too low and needs to be ampli\x0ced. To keep nonlinearities low, thereby preserving pulse quality, the concept of chirped pules ampli\x0ccation is very attractive.'
