382 mW External-Cavity Frequency Doubling 461 nm Laser Based on Quasi-Phase Matching
To rapidly improve strontium optical clocks, a high-power, high-efficiency, and high-beam-quality 461 nm laser is required. In blue lasers based on periodically poled KTiOPO<sub>4</sub> crystals, the optical absorption in the crystals can induce thermal effects, which must be considered...
