Diffusion Bonded Crystal

Bonding (Diffusion bonded)crystals consist of one laser crystal and one or two undoped material. They are combined by optical contact method and further bonded under high temperature. Diffusion Bonded..

Description: Nd:YVO4 is one of the most efficient laser host crystals for all-solid-state laser diode pumped lasers. Its large stimulated emission cross-section at lasing wavelength, high absorption ..

Nd:GdVO4

(Neodymium Doped Gadolinium Orthovanadate ) Nd:GdVO4, is a promising material for diode pumped lasers. Similar to the more well-known Nd:YVO4 crystal, Nd:GdVO4 crystal also exhibits high gain, low ..

Cr4+YAG

Cr4+:YAG Crystal is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Nd:YVO4 or other Nd and Yb doped lasers at wavelength from 0.8 to 1.2 m. Because of its c..

Yb:YAG

It is more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 0.94 m laser output. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a much larger a..

ND:YAG

Description:

Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, typically replaces yttrium in the crystal structure of the yttrium aluminum garnet (YAG), since they are of similar size. Generally the crystalline host is doped with around 1% neodymium by atomic percent.

Advantages Of Nd:YAG：:

•   High gain;
•   Low threshold;
•   High efficiency;
•   Low loss at 1064nm;
•   Good thermal conductivity and thermal shock characteristics;
•   Mechanical strength;

• High optical quality;

• Material characteristics that allow for various modes of operation (CW, pulsed, Q-switched, mode locked).

Applications:

l Nd:YAG can produce blue laser with the frequency-doubling of 946nm;

l Nd:YAG can be operated in a very high power laser up to kw level at 1064nm;

l Nd:YAG can be Q-switched with Cr4+YAG directly;

l Nd:YAG can be used for high power green laser for SHG@1064nm.
