355 nm ultraviolet laser module marking engraving sapphire glass To meet the market demand, RFH newly developed S9 series UV laser in 2020. Comparing with its kinds, S9 series UV laser features with rugged sealed cavity, extremely compact size, simple and robust, high stability, high efficiency, high reliability and excellent laser beam quality.Its compact design suggests no necessity in building big light path, which greatly reduces space and cost and makes it easy to be installed into UV laser marking machines. In addition, S9 series cavity structure is more stability and more excellent scalability, which means the same laser cavity can be produces multi-power lasers , and the stability of different power ranges is greatly improved

10w high power uv laser source engraving marking cutting silicone S9-Y series solid state pulsed UV laser is ultra compact. The whole part of power supply is integrated into the laser head. This makes the size of the laser more smaller, and the integration into a system more easier and convenient. S9-Y series is of short pulse width(<12ns@30k)，superior beam quality(M²<1.2) and perfect laser sport quality(beam circularity>90%).

A few years ago, Mr. Guo from Guangzhou came to RFH to inspect Solid State Q-Switched UV Laser. Today, Mr. Guo came to RFH again for a return visit, and experienced and watched the newly upgraded RFH Solid State Q-Switched UV Laser. Today's RFH Solid State Q-Switched UV Laser adopts more high-end technology in terms of components, and has greatly improved the overall process, reducing the minimum accuracy to about 0.2mm.

Recently, Mr. Huang, a jewelry processing manufacturer from Zhejiang, came to RFH and brought jewelry samples that need to be marked. He hoped to use RFH green lasers to try the samples.

The difference between RFH UV laser marking and traditional ink jet marking is that the UV laser changes the contact marking method, and uses non-contact marking by emitting small light spots. Ultraviolet lasers have the characteristics of short pulses, high beam quality, and high peak power. They are low-temperature cold light sources, and have little thermal impact during marking. They will not damage or burn plastics, which are heat-sensitive materials.

The RFH green laser has unique insights in cutting tempered glass film. The non-contact cutting method only needs to move the emitted light spot on the surface of the tempered glass film to allow the low-temperature cold light source to cut. It only takes a few seconds to cut a tempered glass film, which greatly speeds up the entire production line. .

First of all, the high-power RFH ultraviolet laser uses high energy to divide the glass shell, and its thermal marketing area on the glass is small, and the thermal effect is basically zero, so it will not cause cracks due to the destruction of the tension of the glass during the cutting process .

Gayle, from a laser marking machine manufacturer in South Korea, according to him, the 355nm ultraviolet laser purchased this time is mainly used for laser stripping.
