Wang, M., Zhang, H., Wei, R., Zhu, Z., Ruan, S., Yan, P., Wang, J., et al. (2018). 172 fs, 24.3 kW peak power pulse generation from a Ho-doped fiber laser system. Optics Letters, 42 (19), 4619-4622. https://doi.org/10.1364/OL.43.004619
We demonstrate a high peak power femtosecond fiber laser system based on single-mode holmium (Ho) doped fibers. 833 fs, 27.7 MHz pulses at 2083.4 nm generated in a passively mode-locked Ho fiber laser are amplified and compressed to near transform-limited 172 fs, 7.2 nJ pulses with 24.3 kW peak power. We achieve this performance level by using soliton effect and high-order soliton compression. This is the first demonstration of sub-200 fs pulses, with peak power exceeding 10 kW from a Ho-doped single-mode fiber laser system without using bulk optics compressors.
