Abstract

Utilizing four-level rate equation and double-frequency theory of analogous-Gauss beam, laser output power on the KTP length is calculated for LD array side-pumped 660 nm red laser. The optimal parameters are given. Theoretical analysis agrees quite well with the experimental results. With different length of KTP crystal, 3.75 W red laser power is obtained at 180 W pumping power. Using the appropriate length 5.83 W red laser is obtained at 210 W pumping power.
