Nonlinear crystals

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 (Nonlinear 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.

BBO Crystal

BBO crystal is a nonlinear crystal(NLO crystal) with combination of number of unique features. A-Star Photonics is the original BBO crystals manufacturer who guaranteed 10 days rapid delivery for most dimensions.

LBO Crystals

LBO crsytal (Lithium Tri-borate) is one of the most useful nonlinear optical material not just for its relatively large conversion coefficient – 3x that of KDP, but also for its excellent physical propertie

LiNbO3 & MgO:LiNbO3

LiNbO3 crystals are widely used as frequency doubling for wavelengths 1m and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices. Due to their large


Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (KD*P ) are among the most widely-used commercial NLO materials. They are commonly used for doubling, tripling and quadrupling of Nd:YAG laser at the room


A-Star's KTP crystals feature high purity, low absorption at fundamental and second harmonic generation wavelengths. We supply superior grade and customer-designed KTP crystals for various applications

KTA Crystal

KTA or Potassium Titanyl Arsenate (KTiOAsO4) is an excellent nonlinear optical crystal for Optical Parametric Oscillation(OPO) application. It has better nonlinear optical and electro optical coefficients, significantly reduced absorption in the region of 2μm to 5μm, broad angular and temperature bandwidth, low dielectric constants.
