Northvale, NJ – June 8, 2010 – Photonic Products Group, Inc. (PPGI) zinc germanium diphosphide (ZGP) has outstanding fundamental properties as a mid-IR nonlinear crystal. Especially suitable for high average power applications throughout the infrared region, the large nonlinear coefficient of ZGP, which is approximately 160 times that of potassium dideuterium phosphate (KDP), makes it one of the most efficient nonlinear crystals known.

“Because we grow ZGP in house, we can fabricate, diamond turn and polish various crystal sizes and orientations to exact customer specifications. We also have a number of standard sizes defined for common orientations, in order to simplify manufacturing and ordering.” said John Ryan, Vice President of Sales and Marketing for PPGI.

All crystal growth, orientation, fabrication, polishing and testing of ZGP at Photonic Products Group is done on site, so that customers are assured of complete traceability and satisfaction with every crystal purchased.
