Modern industrial processing depends largely on the use of lasers, especially nanosecond laser. These lasers are known for great peak power, precision, and reliability across a wide range of manufacturing environments. By delivering laser pulses with durations in the nanosecond range, these lasers enable controlled material interaction that balances efficiency with accuracy.This is why they have become indispensable in many industrial applications.
Understanding nanosecond laser
Nanosecond lasers are called so because they emit extremely short pulses of light, typically lasting from a few to several hundred nanoseconds. These short pulses concentrate energy into brief bursts, generating high peak power without excessive heat transfer to surrounding materials. This characteristic allows these lasers to process metals, ceramics, polymers, and composites with minimal thermal damage.
Commonly used nanosecond lasers are solid-state lasers (such as Nd:YAG and Nd:YVO₄), fiber lasers, and diode-pumped systems. They are widely valued for their robustness, long operational life, and adaptability in industrial settings.
Key industrial applications:
Laser marking and engraving on metals, plastics, glass, and coated surfaces. They create high-contrast, durable marks such as serial numbers, barcodes, QR codes, and logos without compromising material integrity. Industries such as automotive, electronics, medical devices, and aerospace rely on nanosecond laser marking for traceability and compliance.
Micromachining and material processing are done with nanosecond lasers and their ability to deliver precise energy control. They are used for drilling, cutting, and structuring materials at micro and macro scales. Applications include PCB drilling, semiconductor processing, thin-film patterning, and precision cutting of foils and sheets.
Nanosecond lasers are increasingly used for laser cleaning, where contaminants such as rust, paint, oil, and oxides are removed without damaging the base material. This non-contact, chemical-free process is gaining traction in manufacturing, heritage restoration, and aerospace maintenance.
