Product Details
V:YAG crystal is a new material of laser saturable absorber and
passive Q-switch in wavelength range of 1.06m-1.44 m. It is
especially suitable for neodymium laser of 1. 3 m. It is an
excellent saturable absorber material in wave band of 1300nm.There
are four chemical values of V element: + 2, + 3, + 4 and + 5. The
V3 + ions with + 3 valence are commonly used Q-switch and saturable
absorbent ions, which are doped into YAG matrix crystals to realize
the passive Q-switch and mode-locking of laser. In the passively
Q-switch solid-state laser, the laser has the advantages of good
stability, long lifetime, miniaturization, simplicity and
practicality.

——growing crystals, linking values
We are seller of crystals. At same time, we are producer of
crystals.
It is a long and arduous process from seed crystal to the desired
single crystal, the composition of the crystal changes through
three states and eventually grows into beautiful crystals. We
witness the growth process of each crystal and clearly know
technologies of each step in the crystal growth process, which
means that we can directly provide customers with crystals that
satisfied customer requirements.
We create value. At same time, we link value.
From company to individual, we all pursue the word "value".
Individual is valuable in society, enterprise is valuable in the
industry. We cherish the existence of value. We hope to set the
enterprise’ value as start pointing, expand to the surrounding,
extend the value from the customer to the supplier. Linking
enterprise and the industry more closer, to create more value.
