This paper presents some valuable results of frequency doubling, considering the transversal variation of the amplitude and the depletion of the fundamental wave power. By solving three dimension-coupling wave equation, the most common expressions of second harmonic wave power are driven. The influences of the fundamental wave power and the crystal length are discussed. As a special example the expressions of second harmonic wave power at low conversion efficiency are given.
