“…The linewidth of the narrow fundamental light source is very important which determines the whole system's linewidth level. To achieve an ultra-narrow linewidth, the Stimulate Brillouin Scattering (SBS) technology are used to compress the linewidth of the laser [12][13][14][15]. A narrow linewidth semiconductor laser is amplified as the pump light to stimulate Brillouin scattering.…”

A single-frequency narrow linewidth green laser at 510 nm is a vital component for the study of Cesium Rydberg atoms. Here, we demonstrate a 510 nm laser based on single-pass second-harmonic generation (SHG) and sum-frequency generation (SFG) via waveguide Periodically Poled Lithium Niobate (PPLN) seeded with a common C-band laser (1530 nm). The final linewidth measured using the delayed self-heterodyne method reaches a narrow linewidth of 4.8 kHz. And, the optical-to-optical conversion efficiency is up to 13.1% and reaches an output power up to 200 mW.
