Abstract
Reported is an ultra-long linear-cavity erbium-doped fibre laser modelocked by a high modulation depth hybrid mirror-based semiconductor saturable absorber mirror with ultra-low repetition rate and highly-chirped output pulses of high energy. With a repetition rate of 250.7 kHz, the laser delivers the single pulse energy of 14 nJ at a pump power of 430 mW. The minimum achievable repetition rate was as low as 25.4 kHz.
