MDFG4: 885-1210nm + 1550nm

MDFG4: 885-1210nm + 1550nm

The MDFG4 is designed for Difference Frequency Generation (DFG) from a 1550nm laser and a tunable 885-1210nm source, for mid-IR generation in the 2-5.5μm range.

Please note:

  • These gratings do not allow phase matching in this regime: 31.35, 32.33, 33.37, 34.48, 35.67, 36.95μm.
  • For lengths 1, 2 and 3mm, the shortest two periods (24.06, 24.63um) cannot be accessed when mounted.
  • 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
