355nm cold dpss uv laser marking qr code on pcb

K-6 series UV DPSS laser, developed and produced by RFH, covers 4W/6W/8W in laser power with short pulse width (<20ns@30K) ,superior beam quality (M²<1.2) and perfect laser spot quality (beam circularity >90%). K-6 series laser is ideal for high-end ultra-precise processing as well as marking in mobile phone shell , package of cosmetics, food, medicine and other high polymer materials, PCB, LCD, glassware surface, metal’s cladding material, plastic keypad, electronic component, gift, communication device, construction material and other areas.

Why RFH UV laser is often used in laser marking plastic button switch? More and more manufacturers choose UV laser marking machine to create pattern and characters on the plastic button switch. The focal spot of UV laser is pretty small with little heat transfer to surrounding material, so UV laser is also called “cold light source”. Because of this feature, heat effect won’t occur. Thus, distorting or burning of materials is no longer an issue.    Professional UV laser manufacturer - Shenzhen RFH Laser Technology Co.,Ltd    With 13 years of experience, the S9 series nanosecond UV laser developed and produced by RFH can engrave clear characters on the keyboard and the mouse. These kinds of characters can not only help people identify different buttons in the dark but also last long, for there are slightly protruding part on the buttons. This improves the durability and practicability of the keyboard and the mouse.

This series of lasers is specially designed for laser marking machines, precision cutting machines, precision drilling machines, laser stripping machine, glass inner winning machine and pan painting equipment. It can meet the laser needs of various applications. The laser wavelength is 354.7 nm, the repetition frequency range is wide, can cover 10kHz to 200kHz. The power range is from 3.0 W to 10.0 W. Importantly, our laser strictly guarantees superior beam quality in all frequency ranges, with m' less than 1.2. This means that our lasers provide excellent beam quality regardless of the frequency used. In addition, our laser has a very small pulse width, less than 12 ns at 30 khz. This means that the heat affected area during processing is small, ensuring accuracy and quality of the results. We adopt a unique q-switched control technology to meet the control requirements of various laser applications. At the same time, our intelligent power control technology makes the operation and monitoring of the laser easy and convenient. You can also communicate with your computer via RS232 to externally control our lasers. Integrated design for easy integration with equipment. Whether you need laser marking, precision cutting, close drilling, laser stripping, glass inner victory or pan judgment paint, our S9-Y-355-10-40-T series lasers can provide you with high-quality laser performance and stable and reliable work.

Shenzhen RFH Laser Technology Co., Ltd. has launched the new Exper III-Y series green laser in 2024. This series features a water-cooled design and is a medium-power nanosecond pulsed 532nm green solid-state laser. It is specifically designed to meet the needs of high-speed precision laser processing production lines, ensuring efficiency and long-term stability and reliability. With its excellent performance and stability, the Exper III-Y series laser will play a crucial role in the field of precision processing, bringing new technological breakthroughs and application prospects to the industry.  

Specializing in the field of high-precision processing, EXPERTIII 355-15-50 series lasers to provide you with a comprehensive and high-quality solution. Whether it is PE/PCB/FPC cutting, or glass, sapphire cutting, or high-definition micro-processing of drilling, marking, cutting, etc. , our laser can meet your needs. Our laser uses an efficient wavelength of 354.7 nm, covering a wide range of repetitive frequencies (10 khz to 200 khz) . Regardless of your application scenario, we provide excellent beam quality (m & LT; 1.2) . Moreover, we guarantee the consistency of beam quality in all frequency range. To minimize the heat-affected region, our laser uses a pulse width of less than 20ns@40k. This means that even at high frequencies, the processing is still excellent. In addition, we also use a unique q-switched control technology to meet the needs of various laser applications, in order to ensure the long life and stable operation of the laser, we also use the internal cavity self-purification system. This makes our laser not only long life, but also stable and reliable operation, in order to facilitate the operation and monitoring, we use the digital intelligent power control technology. This makes your operation easier and allows you to monitor the status of the laser in real time; in addition, our laser also supports communication with the computer and can be controlled externally through the R5232. This gives you more convenience and flexibility in your work. Our EXPERTIII 355-15-50 laser uses an integrated design to provide you with convenient equipment molding. Whether it is a small studio or a large production line, our laser can be perfectly adapted to help you achieve better results.

How can 355nm UV lasers be used in industrial production?   In modern industrial production, laser is an indispensable part. As the requirements for processing accuracy become more and more detailed, lasers are deeply involved in industrial links such as marking and cutting.

Laser engraving glass, green laser or UV laser, which is better   At present, green lasers are widely used in the production of marking and engraving beer glasses, so many manufacturers have accelerated the promotion of production lines, and in fact, RFH UV lasers can also mark on glass.
