What is it about?
Intense short pulses at low repetition rates are a challenging theme with important practical applications, such as optical fibre monitoring. We have shown for the first time the lowest duty cycle while maintaining a low repetition rate and ps-long pulses.

Why is it important?
The stable ultra-low repetition rate without continuos wave (CW) leakage or tail in the output is of extreme importance for many applications such as high-resolution optical-time-domain-reflectometry (OTDR).
