There are three main types of lasers used in 2D laser cutting machine. The CO2 2D laser cutting machine is suited for cutting, boring, and engraving. The neodymium (Nd) and neodymium yttrium-aluminum-garnet lasers are identical in style and differ only in application. Neodymium 2D laser cutting machine is used for boring and where high energy but low repetition is required. The 2d laser cutting machine is used where very high power is needed and for boring and engraving. Both CO2 and 2d lasers can be used for welding.
CO2 2D laser cutting machines are commonly "pumped" by passing a current through the gas mix (DC-excited) or using radio frequency energy (RF-excited). The RF method is newer and has become more popular. Since DC designs require electrodes inside the cavity, they can encounter electrode erosion and plating of electrode material on glassware and optics. Since RF resonators have external electrodes they are not prone to those problems. CO2 lasers are used for industrial cutting of many materials including titanium, stainless steel, mild steel, aluminum, plastic, wood, engineered wood, wax, fabrics, and paper. YAG lasers are primarily used for cutting and scribing metals and ceramics. In addition to the power source, the type of gas flow can affect performance as well. Common variants of 2D laser cutting machines include fast axial flow, slow axial flow, transverse flow, and slab. In a fast axial flow resonator, the mixture of carbon dioxide, helium and nitrogen is circulated at high velocity by a turbine or blower. Transverse flow lasers circulate the gas mix at a lower velocity, requiring a simpler blower. Slab or diffusion cooled resonators have a static gas field that requires no pressurization or glassware, leading to savings on replacement turbines and glassware. The laser generator and external optics (including the focus lens) require cooling.
