摘要：
Boron nitride (BN) nanosheets are prepared using an ultrasonic decomposition method and demonstrated nonlinear absorption characteristics that saturated at near 2 mu m. A passively mode-locked Tm:YAP laser was perfectly implemented with the BN nanosheets as a saturable absorber (SA). In the passively Q-switched mode-locked mode, an average output power of 880 mW with a pulse duration of 478.83 ps was achieved using an incident pump power of 26.46 W, corresponding to an optical-optical conversion efficiency of 3.33%. A pulse peak power of 19.03 W was acquired at 1937.0 nm from the mode-locked Tm:YAP laser.
