Laser systems emit a power level of between >400/450 milliwatts and upwards. These power levels can burn, cut and fabricate most materials including metals. These higher powered laser systems are the candidates for directed energy beam weapons. Class4 lasers require a key switch functioning as remote control access port, time delay and an aperture shutter. and all are off 25% cheap high quality high power green laser. •On/off Key switch. •A protective lens shutter. •Indicator LED, interlock and key switch. •Safe and secure operation. •Outstanding burning ability. •Solid shell with improved heat sink design. •State of the art diode technology. •Built in protective infra red (IR) filter. •Free universal battery charger. •Free Laser Safety Goggles
