Used COHERENT GEM-40A #9290841 for sale

COHERENT GEM-40A is an Nd:YAG(Neodymium-doped yttrium aluminum garnet) laser. It is primarily used for the ablative laser cutting and welding of metallic and non-metallic materials. GEM-40A is a CW(Continuous wave) pumped laser, powered by a pair of frequency-stabilized diode arrays. This ensures a stable output power of up to 40W(Watts). The laser beam is focused by an 80mm beam expander, which has a variable f-stop to adjust the beam size as needed for different applications. The beam diameter can be controlled from 0.5mm to 45mm. COHERENT GEM-40A features an industry leading pulse energy threshold, making it a perfect choice for precision laser cutting and welding applications. The laser has a unique light transmission system that evenly distributes the beam energy for optimum cutting and welding quality. Its pulse energy can be easily adjusted using a rotary knob on the front panel. This versatile feature is ideal for getting precise results in pulse welding and cutting of difficult materials and components. GEM-40A is also equipped with a high resolution scanner system, which allows for precise and efficient line scanning on materials with complex geometry or thin, non-uniform edges. The scanner can be adjusted from a minimum spot size of 20 microns, up to a maximum of 406 microns. COHERENT GEM-40A is a very reliable, easy to use and cost-effective laser for advanced laser cutting and welding applications. Its wide range of applications, high quality output, and user-friendly operation make it one of the most popular lasers in the market today.
