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).

Perspectives

Writing this article was a great pleasure, as it has co-authors with whom I had collaborations for a short time. I hope this article can help researchers in the development and improvement of new optical sources for high resolution applications in fiber monitoring
