Optical Communications, vol. 370, pp. 150–155, (2016) Realization and characterization of single-frequency tunable 637.2 nm high-power laser J. Wang, J. Bai, J. He, and J. Wang We report the preparation of narrow-linewidth 637.2 nm laser device by single-pass sum-frequency generation (SFG) of two infrared lasers at 1560.5 nm and 1076.9 nm in PPMgO:LN crystal. Over 8.75 W of single-frequency continuously tunable 637.2 nm laser is realized, and corresponding optical-optical conversion efficiency is 38.0%. We study the behavior of crystals with different poling periods. The detailed experiments show that the output red lasers have very good power stability and beam quality. This high-performance 637.2 nm laser is significant for the realization of high power ultra-violet (UV) 318.6 nm laser via cavity-enhanced frequency doubling. Narrowlinewidth 318.6 nm laser is important for Rydberg excitation of cesium atoms via single-photon transition.
