RFH green laser for 3D internal engraved crystal


Crystals are divided into man-made crystals and natural crystals, but no matter what kind of crystal it is, it has the characteristics of high hardness and difficult carving, not to mention the very hot inner carving process.


Once the RFH green laser entered the crystal market, it became a very popular new technology for crystal internal carving.


Mr. Liu from Zhejiang recently purchased and ordered an RFH green laser, which was installed on the machine for precise internal carving of crystals.


The ultra-high laser cutting speed makes the cutting edge of the crystal inner carving smooth and smooth without cutting burrs, and the moist cutting effect makes Mr. Liu very satisfied.


The beam stability of the RFH green laser is very strong, the quality of the inner engraving is very high, the characteristics of small thermal deformation and large output energy make it surpass other manufacturers in terms of quality and stability.


In addition, the RFH green laser is completely dust-free during the internal engraving process, which is very friendly to the environment and workers. The simple operation panel makes the use easier and more efficient.


After using it, Mr. Liu praised the effect of RFH green laser. The precise and efficient internal engraving process is extremely high. The crystal internal engraving effect has continuously increased Mr. Liu's orders, brought more customers, and made progress together with RFH in the industry.



Excellent III 532 series green laser characteristics:   

1. 532nm output wavelength, 10 to 200 Hz repetition rate; laser power is 18w-35W; Continuous tuning of repetition rate while maintaining constant pulse energy, superior beam pointing and energy stability make the Excellent III 532 the first choice for micromachining, marking and thin film removal applications 


2. Exceptional beam quality (M²<1.2) ,absolutely assured in all repetition rates; relatively short pulse width <7-8ns@40K with little heat transfer to surrounding material; perfect beam spot quality(Beam Circularity>90%)
