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. ; National Key R&D Program of China (2016YFA0401100); National Natural Science Foundation of China (NSFC) (61605122, 61775146, 61504086); Natural Science Foundation of Guangdong Province (2016A030310049); Shenzhen Science and Technology Program (KQJSCX20160226194031, JCYJ20160428174445840, JCYJ20160427105041864, JSGG20150512162504354); EPSRC (EP/L016087/1); European Union's 7th Framework Programme (631610); Academy of Finland (276376, 284548, 295777, 304666, 312297, 312551, 314810); TEKES (OPEC).
