title: Simultaneous dual-wavelength pulses achieved by mixing spiking and passive Q-switching in a pulsed Nd:GdVO4laser with a Cr4+:YAG saturable absorber.
abstract: A method for generating a dual-wavelength, dual pulse Nd:GdVO4laser at 1.06 μm (F3/24→I11/24) and 1.34 μm (F3/24→I13/24) is proposed. When the 1.34-μm spiking threshold is less than the 1.06-μm Q-switched threshold, the generation of a 1.34-μm spiking pulse leads to a 1.06 μm Q-switched pulse, resulting in a dual-wavelength laser. With a pump power of 11 W, the pulse widths are 89.5 and 427.8 ns for 1.06 and 1.34 μm, respectively, with a 36.5-KHz repetition frequency.
