The laser wavelength drift is caused by standing-wave in the cavity, it can be regarded as a special case of mode instability of longitudinal modes of the laser resonator. Self-sweeping was observed so far in Yb, Er, Tm and Bidoped fiber lasers. We report on Ho-doped fiber laser self-sweeping in interval of 3-5 nm near 2100 nm. The sweeping rate was typically 0.7-0.9 nm/s. The thulium-doped fiber lasers at around 2030 nm and 1950 nm were tested as pump sources. The self-sweeping was registered by FTIR spectrometer and the data processing is discussed Workplace Institute of Radio Engineering and Electronics Contact Petr Vacek, vacek@ufe.cz, Tel.: 266 773 413, 266 773 438, 266 773 488 Year of Publishing 2018
