( KN, KNbO3 )
Potassium niobate is a perovskite type crystal with very strong ferroelectrisity. Its nonlinear optical figure of merit d2/n3, electro-optical and photorefractive figure of merit
n3G/e are the highest among all oxide crystals. Its high chemical stability, high nonlinear optical coefficient and many other unique characteristics make it a ideal NLO crystal used in the field of SHG, EOM, OPO and photorefractivity.
Frequency doublers or blanks with dimensions ( 1 - 10 ) x ( 1 - 10 ) x ( 5 - 10 ) mm3 or larger are available.
