High frequency repetitive marking is the advantage of RFH solid-state UV lasers

The unique function of self-cleaning in the inner cavity makes the RFH UV laser have a longer life and more stable



As long as lasers are mentioned, everyone may think of the same thing. It seems that all lasers have the same origin, but in fact they are different, including but not limited to CO2 lasers, red light, green light, and today's protagonist ultraviolet laser.


In the laser world, UV lasers are also known as "the all-rounder option". Other brothers have their own areas of expertise, but the UV laser is like the Jiuyin Sutra written by Jin Yong. It is an all-encompassing martial arts secrets.


The wavelength of the UV laser is mostly 355nm. Thanks to its characteristics, the spot focusing is extremely small, which can minimize the thermal influence, and the cutting or marking edge can be easily made smooth and burr-free.


It is under such advantages that UV lasers are often used for precision machining and have a wide range of applicability.


In addition to the small heat-affected range, another feature of the UV laser is that it can emerge suddenly and gradually become the mainstream precision machining in the era of Industry 4.0.


Under normal circumstances, ultraviolet lasers are called "cold light sources", and processing using them is also called "cold processing", because ultraviolet lasers can break the chemical bonds in the material or the surrounding medium, so that a non-thermal process occurs in the material. destroy.


Because it is a cold light source, there is no thermal effect, and the material is not easily deformed.


In practical cases, RFH laser can easily cut shells with high-power ultraviolet laser without deformation or burning, and the edges are smooth.


The material of shell is very fragile, and a slight error may fall short. Under the precise control of RFH laser, it is easy to achieve high yield.


In the past, the biggest problem with UV lasers was that the power was too low, and most lasers stayed within 10W. Today, high-power UV lasers above 10W are becoming more and more mature, with higher overall efficiency and more stable performance.


With the popularity of high-power ultraviolet lasers, across various fields, it will soon become an all-around player in the laser industry.


RFH Recommended: Expert III 355 High Power UV Pulsed Solid State Laser


The RFH Expert III 355 is very small in size and adopts an integrated design, which can be easily integrated with the equipment, and it does not need to enlarge the optical path, which saves costs.


In terms of performance, the laser wavelength of the RFH Expert III 355 is 354.7nm, the repetition frequency coverage is wide (single pulse to 200kHz), it has excellent beam quality (M2<1.2), and it is strictly guaranteed in all frequency ranges.


In terms of processing the heat-affected zone, on the one hand, the pulse width is <25ns@50k, the heat-affected zone is very small during processing, and on the other hand, it has perfect spot characteristics (spot ellipticity>90%).


RFH Expert III 355 adopts unique laser cavity design and acousto-optic Q-switching technology, which can be suitable for various laser application control needs.


In addition, an inner cavity self-purification system is also added to the design, which makes the laser have a long life and stable operation.



In actual use, the operation threshold and maintenance difficulty are also one of the problems that laser equipment urgently needs to solve. RFH laser solves this problem very well.



RFH Expert III 355 uses all-digital intelligent power control technology, which is easy to operate and easy to monitor. At the same time, it can communicate with the computer through the RS232 serial port, and control the laser externally, which is convenient for later operation and maintenance management.


After 15 years of ingenious forging, RFH Expert III 355 was born. As a global industrial-grade all-solid-state laser manufacturer, RFH has delivered satisfactory answers to customers.


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.



S9 series uv laser characteristics:   

1. 355 nm output wavelength, Up to 200 Hz repetition rate; laser power ranging from 3w-10w; Continuous tuning of repetition rate while maintaining constant pulse energy, superior beam pointing and energy stability make the S9 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 <12ns@30 with little heat transfer to surrounding material; perfect beam spot quality(Beam Circularity>90%) 

Close to Gaussian smooth beam profile with low value M² < 1.2 and good focusability are beneficial for applications such as
