808nm IR 1000W Microchannel Stack Laser. Micro channel is a way of diode laser bar heat dissipation. It is like a man in summer, lying down on the ice with a full-body surface.Check the following micro channel heat-sink picture. There are several layers of holes for heat dissipation. The micro channel works well and without any burning problems. Usually, we imported this kind of heat sink from Germany with good quality .

low smile effect

Small incision lenticule extraction (SMILE) is a relatively new refractive procedure designed to treat a multitude of refractive errors such as myopia, hyperopia, presbyopia, and astigmatism. The procedure involves using a femtosecond laser to create a corneal lenticule which is extracted whole through a small incision without the use of an excimer laser. It is reported to achieve effects similar to laser-assisted in situ keratomileusis (LASIK) with excellent post-operative outcomes.
