| Abstract: | In this Letter, we demonstrate a nonlinear-mirror (NLM) mode-locked diode-pumped solid-state Nd:YVO4 laser operating at 1342?nm, in which the NLM comprises a periodically poled LiNbO3 crystal and a dichroic mirror. The self-starting threshold for cw mode locking is 1.5?W, which is significantly lower than that of saturable absorber mode locking. An average power of 1.52?W at 1342?nm is obtained under diode pump power of 10?W at 808?nm, with the slope efficiency being up to 16.8%. The pulse width and the repetition rate of the mode-locked laser output are about 9.5?ps and 101?MHz, respectively. |
