Industrial Laser System – Laser Peening System
Compact Laser Shock Peening System
Compact Laser Shock Peening System for Surface Hardening and Fatigue Strength Enhancement
The Compact Laser Shock Peening System is a next-generation surface-enhancement technology engineered to dramatically increase the fatigue life, mechanical strength, and durability of high-value metal components. Designed for demanding industrial environments, this compact solution delivers controlled high-pressure shock waves onto material surfaces using precisely calibrated laser pulses. Unlike conventional shot peening or mechanical processes, laser shock peening (LSP) induces deep compressive residual stresses without altering surface roughness, geometry, or dimensional accuracy. The result is longer component life, improved resistance to cracking, enhanced corrosion performance, and greater operational reliability. With a compact footprint and modular architecture, the system fits seamlessly into research laboratories, industrial test centres, and advanced manufacturing lines. Whether used for prototype development or full-scale production, this LSP platform empowers industries to achieve superior material performance while reducing maintenance costs and downtime. It is an ideal choice for engineering teams seeking validated, repeatable, and industry-proven surface strengthening.
Understanding Compact Laser Peening System
A Compact Laser Shock Peening System operates by delivering ultra-short, high-energy laser pulses onto the target material. These pulses vaporise a thin sacrificial coating, generating a rapidly expanding plasma plume. The expansion creates an intense shock wave that penetrates the material and induces permanent compressive stresses several millimetres deep. This compressive layer significantly retards crack initiation and propagation, making the component more robust under fatigue, wear, and cyclic loading. Compared to mechanical peening, this laser-based solution offers greater precision, deeper stress profiles, and zero contamination. The “compact” nature refers to its integrated design—housing the laser, beam delivery, control unit, and safety systems within a small, industrial-friendly enclosure. It is engineered for ease of use, consistent pulse-to-pulse stability, and repeatability even under continuous operation. This advanced system makes high-level surface engineering possible in laboratories, aerospace units, automotive OEMs, and metallurgical research environments without requiring a large-scale setup.
