The Fiber Laser Revolution

The amazing success of fiber laser technology and its revolutionary impact on laser-based manufacturing bear the hallmarks of more widely publicized technology game changers, such as the displacement of vacuum tubes by the transistor. The analogy is apt when we consider that legacy lasers are bulky, inefficient and short lived devices which are difficult to assemble and require frequent service. Fiber lasers, on the other hand, are compact, highly efficient and robust devices which offer service-free operation through the entire application lifetime.

The True Industrial Laser

The fabulous success over the first 50 years of industrial lasers owes itself to the laser’s ability to convert common sources of energy into highly directed beams. To accomplish this task, every laser is comprised of its energy source, a method of coupling that energy into the laser cavity, and a method of delivering the resultant laser beam to the workpiece. The technical advantages of fiber are apparent in each stage of the architecture.

Energy Source: Legacy lasers utilize numerous energy sources ranging from lamps, RF plasmas and even chemical reactions. Common drawbacks of these energy sources include poor energy conversion efficiency, frequent service requirements and environmentally unfriendly consumables. Fiber lasers utilize long-lived semiconductor diode lasers to efficiently convert electricity into light, and thus require no service or consumables.

Energy Coupling: Conventional laser optical cavities convert input energy within bulky air or gas-filled spaces. Large cavities are necessary due to the inefficiency of gas lasing or the need to insert bulk optical elements within the cavity. Fiber lasers are incredibly compact because they convert semiconductor diode energy into useful laser beams within a fiber no thicker than a human hair.

Laser Beam Delivery: Legacy lasers utilize complex optics to extract the laser beam and deliver it to the workpiece. For example, a sealed window may be needed to isolate exotic or noxious chemicals inside the laser. External steering optics are often needed to deflect the laser output onto its target. In contrast, flexible optical fiber provides an elegant built-in, ideal beam delivery system.

The True Industrial Laser: Both key fiber laser elements, semiconductor diodes and optical fiber, lend themselves to mass production with outstanding process control and repeatability, while the key fiber laser assembly step is fusion splicing of optical fibers. Compare this with the bulky hermetic laser cavities, precision optical alignments and ultra-flat optical surface requirements typical of legacy lasers, and it’s apparent that the simplicity and elegance of the fiber laser accounts for its efficiency, compactness, robustness and low cost which drive its enormous success in the marketplace.
