We report the generation of sub-100-ps pulse trains near the 2.06-μm wavelength in an actively mode-locked diode-pumped Tm–Ho:BaYF laser operating at room temperature. Transform-limited, 97-ps Gaussian pulses at a 100-MHz repetition rate with an average power in excess of 20 mW and with a carrier wavelength tunable by ~50 nm near 2.066 μm are demonstrated.
