Abstract

Reported for the first time is study of a femtosecond Er:fibre laser with recently proposed drop-shaped cavity allowing spectral tuning of output across 78 nm. The developed configuration ensures reliable (without mode locking collapse or output power glitches) and high-quality (signal-to-noise ratio of intermode beats >58 dB) mode locking over the entire tuning range with low variation of output pulse duration (535–770 fs), making this laser a promising tool in applications that require broad-range continuous spectral tuning of femtosecond pulses. An additional feature is the possibility of continuous adjustment of the output pulse repetition rate, important in metrological applications.
