With the increasing popularity of fiber lasers in the cutting and soldering applications of metal sheet metal, users are becoming aware of a weakness in fiber laser pointers: they are susceptible to damage from back-reflected lasers from metal workpieces. If the laser back reflection protection is not strong enough, even if it is designed to withstand the kilowatt-level back reflection, the high-power QBH or QD transport fiber stripped off the fiber cladding, the back-radiated laser beam will pass through the fiber core of the conveyor line. Reflected back into the fiber laser. Even the leading fiber laser manufacturers have experienced a lot of painful lessons, and system integrators have realized that laser fiber combiners, or laser modules, will also be damaged.
As an industrial laser company with a long history and rich experience, Convergence Optoelectronics has been committed to improving and upgrading our industrial lasers. CF series fiber lasers are optical fiber industrial lasers that combine optoelectronics, based on the company's technical experience in backlight reflection protection. We have integrated a set of back-reverse protection technology - CMS technology for CF series lasers, which is based on a unique fiber stripping technology that dissipates the laser at zero point. This technology has been proven to be effective, which also makes Convergence's CF series fiber laser pointer superior to other competitors in terms of back resistance.
Even so, the US engineering team continues to further optimize and upgrade the CF series of backlighting systems, mainly from three convenient improvements and optimizations:
1. The design of the CMS system is upgraded to increase the dissipation efficiency of the backlight reflection, and at the same time increase the number of CMS systems distributed throughout the laser.
2. The use of high temperature resistant materials in CMS systems allows the CMS system to withstand more energy.
3. The backlight reflection protection laser pointer has been re-upgraded, and high-resolution sensors are used, both pulsed and continuous laser energy can be recognized.
Simply put, the new generation of backlight reflection protection system not only can dissipate the reflected light more efficiently, but also can withstand higher energy. At the same time, the upgrade of the sensor also greatly improves the system security.
It can be seen from the following test chart that in the position where the backlight reflection is damaged (see red circle), the (a) point is obviously much brighter than (b), so by comparison, it can be concluded that (b) the stability and anti-reverse ability of the backlight reflection protection. It is stronger than (a). Among them (a) is our previous CMS back protection technology, and (b) is the upgraded technology.
