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)
