Active–passive pulse laser based on gold nanobipyramids at 1.3 μm wavelength

Two-dimensional (2D) materials have attracted intense attention in photonics and optoelectronics for their excellent nonlinear characteristics and are applied for the generation of laser pulses. Here, an active–passive Nd:GdVO41.3 μm laser is realized by using an acousto-optic modulator and gold nan
