Nd:YVO4
WITOPTICS uses CZ technology to grow Nd:YVO4 crystal. With strict control from raw materials and growing process, our Nd:YVO4 is featured with low lasing wavelength absorption and very high efficiency. We supply Nd:YVO4 with Nd doping from 0.27atm%~3.0atm%. Crystals with various size and coating are available. Yttrium vanadate has been growing in popularity because of its high gain, low threshold, and high absorption coefficients at pumping wavelengths, which result from the excellent fit of the neodymium dopant in the crystal lattice. These advantages make Nd:YVO4 is a better choice than Nd:YAG for low-power devices such as hand-held pointers, and others compact lasers. With advanced technology on growing and manufacturing high optical quality Nd:YVO4 crystals, WITOPTICS can provide a wide variety of finished crystals.

Nd:Ce:YAG is a high efficiency laser material that can be widely used in medical, military and meteorology fields. In double doped Nd:Ce:YAG crystals, Cerium are chosen as sensitizer for Nd 3+ ions because of its strong absorption in UV spectral region in flash lamp pumping and efficient energy transition to the Nd3+ excited state. As a result, the thermal distortion is less in Nd:Ce:YAG and the output laser energy is greater than that in Nd:YAG at the same pumping. Therefore, it is possible to realize high power lasers with good beam quality. Lasing wavelength at 1064 nm, laser damage threshold and thermal conductivity of Nd:Ce:YAG crystals are the same as Nd:YAG.
