In the case of low laser power, by means of cylindrical focusing laser beams, energy conversion efficiencies were increased by a factor of 8 to 30 with a maximumconversion efficiency of 64%.
In nonlinear optical frequency conversion process, it is desirable to maximize the product of the intensity of pump laser and the interaction length in order to achieve maximumconversion efficiency.
