Laser Crystal Nd YVO4 Single Axis Crystal Output Is linearly Polarized
Products Description:
Laser Properties: The Nd:YVO4 crystal has large stimulated emission cross-sections at both 1064nm and 1342nm. The stimulated emission cross-section of an a-axis cut Nd:YVO4 crystal at 1064nm is about 4 times higher than that of the Nd:YAG crystal. Although the lifetime of Nd:YVO4 is about 2.7 times shorter than that of Nd:YAG. Because of its high pump quantum efficiency, the slope efficiency of Nd:YVO4 can be very high if the laser cavity is properly designed. In the following Table lists the major laser properties of Nd:YVO4 in comparison with those of Nd:YAG.
| Laser crystal | Doping(atm%) | σ(x10-19cm2) | a (cm-1) | τ (μs) | La (mm) | Pth(mW) | η s(%) |
| Nd:YVO4(a-cut) | 1.0 2.0 | 25 25 | 31.2 72.4 | 90 50 | 0.32 0.14 | 30 78 | 52 48.6 |
| Nd:YVO4(c-cut) | 1.1 | 7 | 9.2 | 90 | 231 | 45.5 | |
| Nd:YAG | 0.85 | 6 | 7.1 | 230 | 1.41 | 115 | 38.6 |
