V:YAG Crystal is a new material of saturable wavelength absorber and passive Q-switch, with a wavelength range of 1.06μm-1.44μm. It is especially suitable for neodymium laser of 1.3μm. It is an excellent saturable absorber material in the 1300nm band. The V element has four chemical values: +2, +3, +4, and +5. +3 valence V3+ ions are commonly used Q-switching and saturated absorption ions, which are incorporated into YAG-based crystals to achieve passive Q-switching and mode-locking of the laser. Among passively Q-switched solid-state lasers, the laser has the advantages of good stability, long life, miniaturization, simplicity and practicality.
