Realizing a high-efficiency 426nm laser with PPKTP by reducing mode-mismatch caused by the thermal effect
TL;DR: A high conversion efficiency tunable laser at 426 nm is reported by adopting an external frequency-doubling cavity pumped by a diode laser and minimizing the variation of beam parameters of the Gaussian beam in the external cavity by optimizing the center of the thermal lens to beam waist.
