摘要

The dual-wavelength pulse dynamics at 1.06 μm and 1.34 μm were reported based on the mechanism of mixed spiking and passive Q switching. When the dynamical behaviors were classified based on the 1.34-μm spiking pulse evolutions in one pulse repetition period of 1.06-μm Q-switched pulse train, the multiple-pulse, leading one-on-one, multiple repetition period pulse, and simultaneously one-on-one dynamics were sequentially generated by increasing the pump power. When the spot size of 1.34 μm emission was varied, the dynamical pulse behaviors occurred in sequence, but the sizes of regions were changed. The experiments agreed with the numerical results.
