Random lasers have broad potential applications in many fields of speckle-free imaging, biological sensing, information security, and optoelectronics due to their unique characteristics of low spatial coherence, flexible design, and simple structure. In recent years, researchers have paid more attention ...
OC: optical coupler; PD: photodetector; AWG: arbitrary waveform generator.2.2 Simulation modelBased on the experimental setup, we also performed corresponding simulations to theoretically analyze the RRFL transient state, including RRFL build-up and dissipation. The simulation model is based on the ...
