LiNbO3 Crystal

Quantity Order:

NLO / EO Crystals --------- LiNbO3

LiNbO3 Crystal 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

Also,LiNbO3 is 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. The transverse modulation
is mostly employed for LiNbO3 crystal.

If the light propagates in z-axis and electric field applies to x-axis, the refractive retardation will be G = p Lnr22V/ l d. The electro-optic coefficients of LiNbO3; are:
r 33 = 32 pm/V, r 31 = 10 pm/V, r 22 = 6.8 pm/V at low frequency
r 33 = 31 pm/V, r 31 = 8.6 pm/V, r 22 = 3.4 pm/V at high electric frequency.

MgO: LiNbO3 and ZnO: LiNbO3 crystals have similar electro-optic properties to LiNbO3 but with higher damage threshold.

The refractive index of an optical medium is altered by the presence of sound, this is called acousto-optic effect which can be used in many devices include optical modulators,switches, deflectors, filters, frequency shifters and spectrum analyzers.
