Different chip holders designed to load nonlinear crystals especially PPLN/PPLT are available: regular types, femto series and WG. The regular chip holders have variable Teflon clips to hold chips with arbitrary width ranging from 1mm to 40mm and are compatible with our oven OV-30D, OV-50D or OV80D.
The Femto series PPLN chip (extreme short PPLN) will be shipped on mount with CD type (~3g) or fs 9605/9610/1410.
WG holder is specially designed for waveguide chips operated with Oven set to allow lens to be very close to waveguide channel facet for easy coupling.
