Where to Buy Sum and Difference Frequency Generators

Nonlinear frequency conversion techniques, such as sum and difference frequency generation, enable the creation of new wavelength components across the infrared, visible, and ultraviolet ranges. These methods are also used to generate terahertz radiation, expanding the versatility of laser sources.

sum and difference frequency generators

HC Photonics (HCP) offers both commercial off-the-shelf (COTS) and custom PPMgO:LN or PPMgO:LT based sum and difference frequency generators (SFG & DFG) for out wavelengths ranging from 355 nm to 5000 nm. The product family includes bare crystals (bulk and waveguide) and plug-and-play fibered mixers.

A reference spec is >2 W at 632 nm from a fibered mixer converting the output of 1064-nm and 1560-nm fiber lasers.

Key features:

  • >200 kinds of commercial off-the-shelf (COTS) crystals with oven/holder for shipping today
  • output wavelength range: 355–5000 nm
  • fibered mixer is single-pass, high-efficiency and optimized for specified input pumps
  • available for fiber or free space as input/output coupling interfaces (such as 2×0, 2×1, 1+0×0, 0+0×0; 0 = free space, 1 = one fiber)
