NLO Crystals is short for Nonlinear Crystals, means the crystals that can generate nonlinear optical effect from laser beam or electricity,magnetic field and strain field.
A-Star’s NLO Crystals include BBO Crystal, LBO Crystal, LiNbO3 Crystal, MgO:LiNbO3 Crystal, DKDP&KDP Crystal, KTP Crystal and KTA Crystal etc. A-Star collect especial carefully for the inside material quality and polish in quickest time.
The BBO Crystal is the most advantage from A-Star Photonics. A-Star can support you 2weeks rapid delivery for most dimensions.
