WebThe poling pattern is lithographically defined and highly customizable allowing crystals to be used in a wide range of applications that require wavelength conversion. Phase-matching over very long propagation lengths at infrared wavelengths is possible with our congruently grown PPLN manufactured from highly uniform Z-axis wafers. Periodic poling is a formation of layers with alternate orientation in a birefringent material. The domains are regularly spaced, with period in a multiple of the desired wavelength of operation. The structure is designed to achieve quasi-phase-matching (QPM) in the material. Periodically poled crystals are frequently used as nonlinear optical materials. They are more efficient at second-harmonic generation than crystals of the same material without periodic structure. The … iobit driver booster free activation key

WebIn a QPM nonlinear wave mixing process, the phase mismatching is compensated by shifting the phase relative to each another among mixing waves over a coherent distance through inverting the sign of the nonlinear coefficient in nonlinear medium (such as “poling” to invert the crystal orientation for fabrication of Periodically Poled Lithium ... WebUsing a third-order QPM can be an alternative way to generate blue light, in which the poling period is 3 times larger than that in first-order QPM. In this work, we report on the generation of a 402.5 nm laser by using cavity-enhanced second-harmonic generation and a periodically poled KTP (PPKTP) crystal with a poling period of 10.02 µm.
