1064nm Crystal Fiber Laser Spares Nd YAG Rod For Laser Welding Machine
Nd YAG Laser Rod / Yag Crystal / Laser crystal rod yag 1064nm Nd YAG Laser Crystal Rod
The ND:YAG continues as the best of the rare earth garnet materials that are characterized by four-level laser operation which permits low threshold pulse and cw operation.
Advantages of Nd:YAG Include:
High gain
Low threshold
High efficiency
Low loss at 1.06μm
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,and cavity dumped)
Our general Nd:YAG production capabilities include:
Slab-Custom Geometries

Nd:YAG(Neodimium Doped Yttrium Aluminum Garnet) has been and continue to be the most widely used laser crystal for solid-state crystal material. Its laser parameters are a good compromise between the strengths and weaknesses of its competition. Nd:YAG crystals are used in all types of solid-state lasers systems-frequency-doubled continuous wave, high-energy Q-switched, and so forth. Compared with others laser crystals, its fluorescence lifetime is twice more than Nd:YVO4, and thermal conductivity is also better
