Abstract
We investigated a dual-wavelength twin-pulse laser with tunable intensity ratio and pulse interval, pumped by an 808 nm laser diode (LD), using Nd: GdVO₄ and Nd: YVO₄ as laser gain media, in conjunction with a Cr⁴⁺:YAG saturable absorber. A new theoretical model of a dual-wavelength twin-pulse laser based on intracavity gain-switched pumping has been established. The findings of the simulation show that it is possible to accomplish dual-wavelength twin-pulse laser output without gain competition. Moreover, the simulation underscores the capability to fine-tune the intensity ratio and the pulse interval between the two wavelengths. In the experiment, theoretical modeling served as a guide for key parameter settings. Ultimately, dual-wavelength twin-pulse laser outputs at 912 nm & 1064 nm were achieved, with a tunable intensity ratio ranging from 0.8 to 1.4 and an adjustable pulse interval from 18 to 6 ns. The experimental results aligned closely with the simulation outcomes.
