LiNbO3

Quantité : 999

Lithium Niobate(LiNbO3) Crystal is widely used as frequency doublers for wavelength >1um and optical parametric oscillators (OPO) 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, LiNbO3 is also widely used as electro-optic modulator and Q-switch for Nd: YAG, Nd: YLF and Ti: Sapphire lasers as well as modulator for fiber optics, etc.

Crysmit can also provide MgO: LiNbO3 and Fe: LiNbO3.
