“…A large part of the gain is used to compensate for the loss introduced by the interference filter. In agreement with previous work, we could easily lower these intracavity losses by increasing the spectral width of the interference filter [9]. The pulse spectrum measured at the exit and the input of the fiber as well as the spectrum rejected and transmitted by this filter is shown in Fig.…”

“…Both dissipative soliton as well as similariton mode locking have been reported [3,5]. These techniques make it possible to design powerful and compact fiber lasers [6][7][8][9]. Along this line, an ytterbium fiber oscillator delivering pulse with duration of ~2.1 ps with energy of ~0.9 µJ at 76.5 MHz high repetition rate has been reported very recently [10].…”

We have designed an ytterbium rod-type fiber laser oscillator with tunable pulse duration. This system that delivers more than 10 W of average power is self mode-locked. It yields femtosecond to picosecond laser pulses at a repetition rate of 74 MHz. The pulse duration is adjusted by changing the spectral width of a band pass filter that is inserted in the laser cavity. Using volume Bragg gratings of 0.9 nm and 0.07 nm spectrum bandwidth, this oscillator delivers nearly Fourier limited 2.8 ps and 18.5 ps pulses, respectively. With a 4 nm interference filter, one obtains picosecond pulses that have been externally dechirped down to 130 fs.
