2 μm passive Q-switched mode-locked Tm 3+ :YAP laser with single-walled carbon nanotube absorber

Journal Article

We report the first demonstration, to our knowledge, of passive Q-switched mode-locking in a Tm 3+:YAP laser, operating in the 2 μm broadly spectral region formed with a compact Z-flod cavity. A transmission-type single-walled carbon nanotube saturable absorber (SWCNTSA) is used for the initiation of the pulse generation. The repetition rate of the Q-switched envelope was 60 kHz at the pump power of 8.6 W. The mode-locked pulses inside the Q-switched pulse envelope had a repetition rate of ∼92 MHz. A maximum average output power of 761 mW was obtained. The dependence of the operational parameters on the pump power was also investigated experimentally. © 2011 Elsevier Ltd. All rights reserved.
