Nd:YVO4 crystals «In Stock»

Compared to Nd³⁺:YAG crystals, the Nd³⁺:YVO₄ crystal has much higher absorption and emission cross-sections, a broader gain bandwidth and wavelength range for pumping, a shorter upper-state lifetime, a higher refractive index, thus it is characterized by a lower thermal conductivity. Nd:YVO₄ crystals are well suited for passively mode-locked lasers with high pulse repetition rates. A drawback of Nd:YVO₄ lasers are that it is impossible to achieve pulse energies as high as it is achievable with Nd:YAG lasers at Q-switched operation, due to the lower upper-state lifetime and higher gain efficiency. In conclusion, Nd:YVO₄ is better suited as an active medium of high pulse repetition rate Q-switched lasers and CW lasers with a lower lasing threshold.
