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 temperature and power is investigated. The second-harmonic-generation power for different temperature and different fundamental power are analyzed. The influence of optimized matching temperature for fundamental power is investigated.

Key words: Periodically poled KTiOPO4, Second-harmonic-generation power, Fundamental power, Crystal temperature
