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.
