V:YAG(V-doped yttrium aluminium garnet) – Passively Q-switched Crystal – Customized Products
V:YAG crystal, also known as V-doped yttrium aluminium garnet crystal, with the chemical formula of V3+:Y3Al5O12. It is a new laser saturable absorber and passive Q-switch crystal product with good comprehensiveness.
It is widely used in laser plotters, rangefinders, laser cutting machines, and other fields. In the passive Q-switched solid-state laser, the laser has the advantages of good stability, long life, miniaturization, simplicity, and practicality.
Element V has four chemical valences: +2, +3, +4 and +5. V3+ ions with +3 valence are commonly used as Q-switches and saturable absorption ions.
They are doped into YAG matrix crystals to achieve passive Q-switches and laser mode-locking. V:YAG crystal is a new material of laser saturable absorber and passive Q-switch, and its wavelength range is 1.06μm – 1.44μm.
Particularly applicable to 1.3 μm Nd laser. It is an excellent saturable absorber at 1300 nm.
