High-power lasers are used in a diverse range of applications spanning industrial manufacturing, military defense, scientific research, and medical procedures.
Industrial Applications
High-power lasers excel in industrial settings due to their precision, speed, and ability to work with various materials.
- Cutting: Lasers precisely cut metals, plastics, ceramics, and composites.
- Welding: Laser welding creates strong and precise welds with minimal heat-affected zones.
- Engraving/Marking: Lasers quickly and accurately engrave or mark materials for identification, decoration, or functional purposes. This is faster and more precise than other methods, enabling the processing of intricate parts more efficiently.
- Surface Treatment: Lasers can modify the surface properties of materials, enhancing hardness, wear resistance, or corrosion protection.
- Additive Manufacturing (3D Printing): High-power lasers are used in processes like selective laser melting (SLM) and stereolithography to create three-dimensional objects layer by layer.
- Cladding: Applying a layer of material onto another, enhancing its properties or repairing damage.
Military Applications
High-power lasers are being developed for several defense applications.
- Directed Energy Weapons: Lasers can be used to disable or destroy targets, such as drones, missiles, or vehicles.
- Target Designation: Lasers can accurately mark targets for other weapons systems.
- Missile Defense: High-energy lasers can intercept and destroy incoming missiles.
- Surveillance and Reconnaissance: Lasers can be used for long-range imaging and detection.
