Wide Range Of Light Transmission LiNbO3 Commonly Used Material For Pockels Cells, Q-Switches
Product overview:
LiNbO3 Crystal is widely used as frequency doublers for wavelength > 1 mm and OPOs pumped at 1064 nm as well as QPM devices.
LiNbO3 Crystal is widely used as frequency doublers for wavelength>1 µm and optical parametric oscillators(OPOs) pumped at 1064nm and quasi-phase-matched(QPM)devices.Additionally due to its large Electro-Optic (E-O)and Acousto-Optic(A-O)coefficients.
LiNbO3 is the most commonly used material for Pockels Cells,Q-Switches and phase nodulators,wavwguide substrate,and surface acoustic wave (SAW)
wafers,etc.we can provide high quality and large size LiNbO3 crystals for all of these applications.
