Abstract:In this paper, we present second-harmonic generation at 518 nm of a narrow-line-width picosecond fiber laser at 1036 nm in crystal of periodically poled KTiOPO4 . The characteristic of tempera-ture and power is investigated. The second-harmonic-generation power for different temperature and dif-ferent fundamental power are analyzed. The influence of optimized matching temperature for fundamental power is investigated.
Keywords:Periodically poled KTiOPO4 Second-harmonic-generation power Fundamental power Crystal temperature
