Optical LiNbO3 Crystal Lens - (linbo3)

Lithium niobate(linbo3) crystal lens is widely used as frequency doublers for wavelength > 1 mm and optical parametric oscillators (opos) pumped at 1064 nm as well as quasi-phase-matched (qpm) devices. Due to its large electro-optic (e-o) and acousto-optic (a-o) coefficients.
we manufacture linbo3 crystal lens professionally.
