Phase matching curve for MDFG3-1.0-XX
Please note these are calculated tuning curves only and actual values may vary.Key Features
The MDFG3 is designed for Difference Frequency Generation (DFG) from a 1064nm laser and a tunable 1480-2128nm source, for mid-IR generation in the 2.1-3.8µm range.
The output wavelength can be tuned with each PPLN grating by adjusting the input laser wavelength and varying the PPLN temperature.
Have a question- Multi-band AR coated
- Flatness <λ/4@633nm
- Parallel to ±5 minutes
- Better than 70:30 mark-to-space ratio
- Polished to 20-10 scratch dig
- Fewer than two 100μm edge chips per facet

PPLN Oven Mount Adapters
For easy integration into your optical arrangement, Covesion provides a flexible range of oven mounting adapters for post mounting solutions or flexure stage solutions, as well as a small compact mount for oven-free arrangements.
Temperature Controller
For high stability temperature control, the Covesion OC2 is a compact stand-alone bench-top unit for use with our PPLN oven range.
PPLN Ovens
For fixed wavelength applications PPLN should be maintained at a constant operating temperature for maximum conversion efficiency. In tunable wavelength applications the temperature of the crystal can be adjusted for fine wavelength tuning.
