Abstract

Through in-depth analysis of the second harmonic nonlinear conversion efficiency, using periodically poled crystal MgO:sPPLT as the research object, combining the Sellmeier equation and the polar period with temperature thermal expansion relationship, the best matching temperature is obtained when the fundamental laser is normal incidence into the periodically poled crystal. When the fundamental laser tilt incident, equivalent polar period becomes larger, the best matching temperature is reduced. Temperature and wavelength accept bandwidth can be obtained conveniently using the normalized frequency doubling efficiency curves for given length of frequency doubling crystal. The crystal length becomes longer, temperature and wavelength accept bandwidth will become narrower. These conclusions are useful for other periodically poled crystals and are guidances for cw fiber laser external cavity frequency doubling. As long as the Sellmeier equation and polar period with temperature thermal expansion relationship are known, the method used in this study can be extended to other periodically poled crystals.
