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.
