Detailed explanation of Covesion's PPLN crystal for more efficient wavelength conversion

This video mainly introducesPPLN crystalandEncapsulated waveguideRelated products. Firstly, the selection of crystal length is crucial for different application scenariosThe longer the crystalThe higher its conversion efficiency, the narrower its receiving linewidth at the same time. Therefore, continuous light is usually suitable for selectionThe longer the crystalThe plan aims to achieve higher conversion efficiency; Femtosecond lasers, on the other hand, are suitable for shorter crystals because they have a larger receiver linewidth and are more effective in achieving frequency doubling. Secondly, professional temperature control equipment should be used during use to ensure that the crystal operates in a stable temperature environment. In addition, it also specifically introducedEncapsulated waveguideThe product, packaged waveguide, is compact in size and easy to integrate into the system. The semiconductor temperature controlled waveguide can support higher optical power input, making it suitable for customers with high power requirements.
