BOWKET Multifunctional 808 Diode Laser And YAG Laser HL-AS15, Contact sales@bowei-ch.com for more; Advantage: 1、Laser: Use the world's top vertical stack laser ① Long service life: 10 million times of continuous light emission; 2、Efficient and stable refrigeration system The laser refrigeration system adopts constant temperature cooling, which can ensure that the entire system continues to work 7*24 hours. The air-cooling + water-cooling method commonly used in the market can only work continuously for 2-3 hours. 3、Adopting contact type sapphire cooling system, efficient cooling transmission efficiency, making the skin more comfortable during treatment 4、Intelligent water temperature control system: avoid excessive water temperature and damage to the handle。 5、Unique shape design and color matching make the product more beautiful and fashionable。 6、The distance traveled by the honeycomb picosecond laser is very, very short, which means that the more selective the treatment, the higher the safety, and the shorter the number of treatments, the stronger the curative effect! The honeycomb picosecond laser can reduce it It is crushed into fine sand, so that the absorption efficiency of pigment fragments is greatly improved, the treatment time and the number of treatments are greatly shortened, and the freckle effect is more obvious. 1 second s=1000 milliseconds ms, 1 millisecond ms=1000 microseconds us, 1 microsecond us=1000 nanoseconds ns 1 nanosecond ns=1000 picosecond ps 1 second s=1,000,000,000,000 picosecond ps
