808nm Diode Laser History in China 808nm diode laser was developed in 2012, Micro-Channel was recommended from year 2012 to year 2015, as we know, Micro-Channel has the best cooling system. However, Micro-Channel has been rejected to use after year 2015 because of following reasons. The cost for micro-channel laser lar is very expensive, and it is very difficult for the market to accept to buy a diode laser machine at more than usd7000. In order to meet the market’s price need, less power laser mould was needed, such as 200W, 300W, 400W Micro-channel laser mould has been installed, which cause painful experience. 70% patients rejected to do treatment because of the painful hair removal. Micro-Channel has very high requirement for the water quality, it is necessary to have partical filter and deionizer filter. However, it is very easy to burn chip if the water quality is not high. High requirement on the soldering between chip and sub-mount. The soldering material is also very important, the technology in China at that time is not so nature, which causes a lot of after sales. Even for the Alma laser supplier, it will be dead after 40 million shots.

Above disadvantages made the supplier focus on Macro-channel. In this case, most of suppliers have recommended Macro-channel since year 2016. Compared with micro-channel laser bar, after sale rate of macro-channel laser bar has decreased a lot. However, it still has following problems. As the cooling is not so good as micro-channel, it need more size heat-rink material for hot radiator, which makes the handpiece heavy, and some beautician can’t take it any more after 3 hours. As the cooling is not so good as micro-channel, it needs high water flow-speed for the water pump, it should make sure more than 4L/Min. Which also makes the noise. Of course, the most important is, diode laser has been developed for several years, macro-channel laser bar, like the standby solution, to replace the micro-channel, especially for the distributor, it is no significant to get the order through quoting cheaper price in the competitor.

In this case, this year we pushed the latest technology-Super Channel, which combines the advantages of Micro-channel and Macro-Channel Cooling system is as good as Micro-channel Low flow-speed for the water pump The same water quality as Macro-channel Light handpiece Add Fast Axis Collimation from Limo technology, without light guided system. Light and Smart design The most important is the warranty is two years, and no shots limitation. This solution has been tested well.
