Square pulse emission with ultra-low repetition rate utilising non-linear polarisation rotation technique

Square pulse emission with ultra-low repetition rate utilising non-linear polarisation rotation technique

The generation of nanosecond square pulse and microsecond harmonic pulse in a passively mode-locked fibre ring laser is demonstrated by inserting a 20 km long single mode fibre in the cavity. The laser operates in anomalous region based on the non-linear polarisation rotation process. The square pul...
