A1 Jiménez Rodríguez, Marco A1 Monroy, Eva A1 Corredera, Pedro A1 González Herráez, Miguel A1 Naranjo Vega, Fernando Bernabé A1 Ania Castañón, Juan Diego K1 Fiber lasers K1 III-V semiconductors K1 Indium compounds K1 Locks (fasteners) K1 Electrónica K1 Electronics AB We demonstrate ultrafast harmonically mode-locked fiber lasing in up to 6-km-long rings at 1.56μm with InN SESAM. Fundamental mode-locking with pulse width of 239fs, pulse energy of 155nJ and peak power of 650kW is achieved with a 1-km-long cavity.
