Product Description
High Power laser rod 8x185 8x165nd yag rods rotary engraving machine laser marking machine parts
Nd:YAG Laser Rod
ND: YAG crystal rod is used in Laser marking machine and other laser equipment it is the only solid substances that can work continuously at room temperature, and is the most excellent performance laser crystal. It is widely used as a solid-state laser materials. YAG rod's role is to generate a laser, with the partial and full reflect mirror on both ends ,YAG rod can produce a stable and continuous laser, it is the core part of YAG and fiber laser.


Nd: YAG laser wavelength is 1064nm, it can be used in military, medical, industrial and other fields.We provide YAG laser rod with a stable high optical homogeneity, high consistency, more precision, long life characteristics.The diameter of the laser rod is from 1mm-35mm with 0.5mm ladder increase. Length size from 0.3mm-230mm,normal size 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 70mm to 200mm. combination of diameter and length is all available.
Advantages of Nd:YAG crystalsHigh gain, low threshold, high efficiency1064nm light absorption is low, high optical quality, low lossHigh mechanical strength, Good thermal conductivity and thermal shock characteristicsSuitable for all kinds of laser working mode (CW, pulse, Q switch, mode locked ,cavity dumped, frequency doubling, etc.)Suitable for high average power solid state laser
Main Applications
CW LasersPulsed Lasers Q-switched Lasers
Mode Locked LasersCavity Pumped LasersHigh average power Laser
Typical Applications
Produce blue laser with the frequency-doubling of 946nm
Be Q-switched with Cr:YAG directlyi
Be operated in a very high power laser up to KW level
Further optical processing of Laser rod

Grooved rod
Using optical processing technology, further optimizing the performance of the material.
(1)Efficiency increases 10%-20%;
(2)Heat effect is reduced;
(3)Beam quality improvement.
Cylindrical polishing
Improve the material application performance, improve the beam mode, suitable for the use of TEM00 mode.
AU coated
Both ends of laser are AU coated,which reduce the thermal effects so as to improve the beam quality.
(When purchase Nd YAG Laser Crystal Rod for Solid State Laser, please inform us the size,coating and your application if possible. For further understanding of the situation, please contact me.)

Different size Nd:YAG laser Rod
Nd:YAG Rod and SlabOptical Resonant Cavity
The Nd YAG Laser rod is fixed in the laser cavity.
The longer the rod is, the bigger the power is.
Working Principle
The lamp light first, the light is reflected by the golden cavity into YAG rod, the rod will generated the 1064nm laser.
