Abstract
By simultaneously employing both an electro-optic modulator and carbon nanotube saturable absorber (CNT-SA) in a dual-loss modulator, a subnanosecond single mode-locking pulse underneath a Q-switched envelope with high peak power was generated from a doubly Q-switched and mode-locked (QML) Nd:Lu0.15Y0.85VO4 laser at 1.06 μm for the first time, to our knowledge. CNTs with different wall structures—single-walled CNTs (SWCNTs), double-walled CNTs (DWCNTs), and multi-walled CNTs (MWCNTs)—were used as SAs in the experiment to investigate the single mode-locking pulse characteristics. At pump power of 10.72 W, the maximum peak power of 1.312 MW was obtained with the DWCNT.
