Wavelength Conversion Module for 780nm Light Generation
Photonics

NEL produces periodically poled lithium niobate(PPLN) waveguide modules for 780nm second harmonic generation(SHG). The module consists of a PPLN waveguide, a thermoelectric cooler, and a thermistor. A phase matching bandwidth (FWHM) of a standard 34mm-long waveguide module is 0.36nm at pump wavelength. A temperature coefficient for the wavelength tuing is 0.1 nm/deg C.

FEATURES

  • SHG wavelength   780nm
  • Conversion efficiency   >100% / W
