SFG-775-5-BC is a 5 mm Periodically Poled Lithium Niobate(PPLN) waveguide modules for near-IR, and mid-IR light generation. The module has a PPLN waveguide with built-in TEC and a Heatsink. A custom design of the poling period is available. This module may be pumped in 1550 nm wavelength window for up-conversion of photons to the 775 nm region. Due to the large nonlinear optical coefficient and the well confined optical waveguide structure in the Z-cut Lithium Niobate, the SFG-775-5-M allows high up-conversion efficiency. The spectrum of the output may be tuned by either slightly tuning the pump laser wavelength or by adjusting the temperature of the SFG-775-5-M. Please specify your pump and SHG/SFG/DFG wavelengths down to 775 nm when ordering modules.
