Like other types technology, laser cutting has evolved over the years. As such, fabricators can now offer various types of laser cutting service depending on which technology they have available.
Gas Laser Cutting
Gas laser cutting, also known as CO2 laser cutting, is the most widely used type of laser cutting service. This process involves electrically stimulating the carbon dioxide gas mixture to create gas lasers. In the past, gas lasers aren’t powerful enough to cut through metals. As such, laser cutting service back then is limited to cutting plastics and non-metallic materials.
However, laser cutting technology has evolved and now makes use of nitrogen as well. This makes them capable of cutting through metals like steel and aluminum. Many of the metal or aluminum store sign that you see around are made using this process. Other materials that can be cut with gas lasers include wood, glass, acrylic, and several others.
Crystal Laser Cutting
Crystal laser cutting involves the use of lasers made from neodymium-doped yttrium aluminum garnet (nd:YAG) and neodymium-doped yttrium ortho-vanadate (nd:YVO). These crystals are what make this type of laser cutting service highly powerful. They are mostly used to cut metals, coated metals, and plastics. Some crystal laser cutting technologies also allow for cutting ceramics.
Crystal laser cutting service though can be quite expensive. This is because the machine and the pump diodes are costly—an overhead expense that service providers are sure to pass on to their clients.
Fiber Laser Cutting
Fiber laser cutting is a technology that involves the use of a foundation laser or what is called ‘seed laser’. This is then amplified by a glass fiber and pump diodes to create a stronger laser beam. In fact, fiber laser is seen to be a hundred times stronger than gas lasers. Fiber lasers used by laser cutting service providers can be used to cut both metal and non-metal materials.
One of the biggest advantages of fiber lasers is that they create an extremely small focal diameter. This makes them suitable for other services aside from laser cutting service like metal marking, annealing, and engraving.
Whatever technology is used, laser cutting service is a cost-effective and efficient alternative to conventional cutting methods. Slicing through various types of materials with precision and proficiency, laser cutting will fit virtually any application.
