Laser Cutting systems have been around since first experimented in the 60s. Lasers can be used to cut a wide array of different material from Metals, Wood, Plastics, Stones and other materials. Advancements in the design and engineering have led to a number of lasers on the market today. The most common, sought out, type of Laser in the metal cutting industry are C02 and Fiber (Solid State) lasers.
Why are Co2 Lasers a better fit for application over Fiber Lasers?
C02 Lasers are based on a gas mixture that is electronically stimulated. A high intensity light produces the Laser beam. This Infra Red beam is bounced of several mirrors that are position at different angles. The focus laser beam then makes the desire cut while High-pressure gasses are used to blow off the excesses material. Theoretically C02 Lasers have more versatile capabilities.
C02 lasers have the capability to cut thin-to thick material with ease. Preferably used for its faster cutting speeds on material thicker than 1/4”, leaving a smoother surface. The major Down-point is the consumable items, such as optic lenses, gasses and operating cost. However advances in regards to the maintenance aspect have essentially resolved some issues making this machine maintenance free. Another point to look into is C02 lasers cannot process reflective material as well as Fiber Lasers because cutting copper and brass and other like material damages the optics on the machine. If you have heavy-duty projects with material thicker than 1/4” we suggest you go with a C02 laser.
Why choose a fiber laser over a C02.
A variation of the solid-state laser, Fiber Lasers, uses a clad fiber cable that has light emitted to the central core of the fiber to produce the high intensity light. Most Commonly diodes are optically pumped into the Cavity mirror on Fiber to create the laser beam. The Fiber laser diodes can be end or side pumped.
Fiber Lasers machines have a 50% longer servicing intervals as well as half the servicing cost as oppose to the C02. The new advance technology on the fiber lasers requires less maintenance and also far less operating costs as compared to the C02. With fiber lasers one can cut Copper, Brass, Stainless Steel and aluminum without damaging the Focusing Lens. Fiber lasers advantage is cutting material up to 1/4 thick. Fiber lasers have 3-4 times faster cutting speeds when cutting mild, galvanize and Stainless Steel as opposed to C02. If you have a lot of light duty projects with reflective material thinner than 1/4” we suggest you go with the Fiber Laser. However Fiber laser systems can certainly cut thicker material just not as fast as a C02 on material thicker than 1/4”
