We present a theoretical and experimental study on PM ultra-short fiber laser cavities operating at low repetition rate. The mode-locking operation in this study always relies on SEmicondutor Saturable Absorber Mirror (SESAM) and intracavity spectral filtering. Several experimental configurations have been tested and modeled. Repetition rates as low as 7.7 MHz with sub-picosecond pulse duration have been obtained. A longer cavity has also been modeled in order to determine if stable ultra-short pulsed operation would also possible at lower repetition rates.
