Types of Industrial Lasers
Carbon Dioxide Lasers
CO2 lasers were among the earliest industrial lasers developed and are still widely used today due to their high power output and reliability. These lasers typically operate in the infrared spectrum at a wavelength of 10.6 μm. CO2 lasers are commonly used for applications like cutting, engraving, welding and heat treatment of a variety of materials such as plastics, textiles, wood, metals and ceramics.
Solid-state lasers use a solid gain medium, usually a crystalline or glass host material doped with ions like neodymium, ytterbium or erbium. These lasers are highly efficient, compact and durable making them ideal for industrial uses. Some common types include Nd:YAG lasers operating at 1064 nm and fiber lasers at 1070 nm. They are utilized extensively for marking, cutting, welding and additive manufacturing applications.
Advancements in fiber laser technology have enabled higher power outputs from more compact packages compared to traditional lasers. Fiber lasers consist of active optical fibers doped with rare-earth elements like ytterbium and erbium. Their flexibility, reliability and low maintenance needs have rapidly increased their adoption across various industries. Major application areas of fiber lasers include cutting, welding, drilling and microprocessing.
Excimer lasers utilize noble gas halide combinations like argon fluoride (ArF) and krypton fluoride (KrF) that emit in the ultraviolet spectrum. Their shorter wavelengths allow highly precise processes like semiconductor material processing, micromachining and lithography. Excimer lasers find extensive usage in MEMS manufacturing, solar cell production and circuit manufacturing.
