What's VCSEL?
VCSEL is short for Vertical cavity surface emitting laser diode, with a big surface for emitting and heat spreading, it can burden temperature over 85℃. Thus it's quite stable.
Since 2014, Laserconn first adopted VCSEL on hair removal applications and got patent from US and Europe. This is a revolutionary breakthrough in this filed, it’s replacing 60% market of the LD bar during the past 10 years.
Meanwhile, we adopt the VCSEL tech on all the production line. Including Alex755 Hair removal, Q-switched laser system for Tattoo removal, Laser therapy, Laser slimming etc. Each time we launch any new product, it’s a new trend in the market. With such cutting edge tech development, we are ahead of other competitors 3-5 years.
