· Nd:YVO4 (Neodymium Doped Yttrium Orthovanadate), one of the most efficient crystals for diode pumping lasers especially for medium and low power density. Comparing with Nd:YAG, Nd:YVO4 has higher absorption coefficient to pumping light and larger stimulated-emission cross section. Nd:YVO4，coordinating with LBO, BBO, KTP nonlinear crystals, is able to obtain good frequency doubling making it an excellent crystal for all-solid-state lasers for near infrared, green, blue or ultraviolet ray output.· Basic Properties· Point Group D4h· Mohs 4—5 And glass similar· Density 4.22g/cm3· Thermal Expansion Coefficient αa=4.43×10-6/K αc=11.37×10-6/K· Thermal Conductivity ⊥C: 51mw/cm.k //C: 52.3 mw /cm.k(300k)· Laser Wavelength 1064nm,1342nm· Thermal Optic Coefficient dna/dT=8.5×10-6/K dnc/dT=3.0×10-6/K· Stimulated Emission Cross-Section 25×10-19cm2 @ 1064nm· Fluorescent Lifetime 90μs(about 50 ms for 2atm%Nd doped)@ 808 nm· Absorption Coefficient 31.4cm-1 @810nm· Intrinsic Loss 0.02cm-1 @1064nm· Gain Bandwidth 0.96nm-1@1064nm· Polarized Laser Emission π polarization; parallel to the optic ¹ Dimension tolerance: ( W ±0.1mm) ×（H ±0.1mm）×（L﹢0.5/-0.1mm）(L≥2.5mm) Clear aperture: ≥90% Flatness: 1 for 1064nm, TEM00, 10ns, 10 Hz (AR-coated)
