Diffuse-reflection Pumping Cavity
Two key technologies have been used in the pumping cavity. Firstly,
SFG-silicate glass is used as a filter to prevent the color centers
and reduce the thermal effects in the laser medium. Moreover,
SFG-silicate glass
has a strong absorption at the emission peak of Nd3+, which is
helpful to reduce the radial ASE and increase the stored energy in
gain medium. Secondly, the reflector is diffuse type. By optimizing
the pumping structure, uniform pumping distribution and high
pumping efficiency are achieved, which is very important for good
beam quality. This kind of pumping cavity is a perfect choice for
high-energy laser system with high repetition.

——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.
