# Opt Lasers > Manufacturer of blue laser systems since 2014, based in Warsaw, Poland (EU). Over 6,000 blue lasers sold for industrial use over the last 10 years. Opt Lasers holds a granted Polish patent (P.438308) for a multi-laser-diode laser head for engraving and cutting. Opt Lasers' blue lasers were used in the first scientific blue-laser weeding trials, and Opt Lasers was the first company in the world to supply blue laser technology for commercially operating laser weeding machines. The company specializes in multi-laser-diode blue laser technology across laser weeding systems, CNC laser heads and upgrade kits, high-power blue laser sources, laser diode modules, laser diode drivers, and temperature controllers. Opt Lasers serves CNC machine makers upgrading mills and routers into laser engravers and cutters, builders of agricultural laser-weeding machines, OEM integrators sourcing blue laser modules and diode drivers, and researchers in biosciences and photonics. Product families cover blue lasers, CNC laser upgrade kits, free-space and fiber-coupled laser diode modules, laser diode drivers, TEC temperature controllers, laser diodes, and beam-shaping optics, alongside application and buyer guides for wood, metal, acrylic, leather, carbon fiber and more. ## Laser Weeding -
