    Frequency doubling

    It's just a simple Conversion, Right?

    Conversion of NIR laser source light into light in the green-blue spectral range can be carried out by using SHG, also known as frequency doubling techniques, a technology generally known in the laser-based optical industry. A reasonable goal for single-pass conversion efficiency is that it should be in ~25% range to avoid excessive laser cost. Conversion efficiency is proportional to input power, the square of the effective nonlinear coefficient of the nonlinear element (crystal) and the length of the nonlinear element.

    r33 is the same? conversion efficiency (SHG)
