Abstract
We have demonstrated a simple technique to make continuous wave (CW), tunable visible lasers. In this experiment, the output from a CW, tunable Raman fiber laser (RFL) is frequency doubled using LBO crystal in a single pass configuration. By tuning the output wavelength of RFL from 1.1-1.3um visible light in green to red wavelengths are generated. The efficiency and output power can be substantially improved by placing the crystal within a resonator cavity and pumping using a polarized RFL with narrower linewidth. Also, by tuning the operating wavelength of Yb laser (1060-1100 nm) broadband visible wavelength tunability can be achieved. © 2020 SPIE.
