Compact Laser Shock Peening System
Compact Laser Shock Peening System for Surface Hardening and Fatigue Strength Enhancement
The Compact Laser Shock Peening (LSP) System is a next-generation surface enhancement technology engineered to significantly improve the fatigue life, mechanical strength, and long-term durability of high-value metal components. Designed for demanding industrial environments, this advanced system generates precisely controlled high-pressure shock waves using calibrated laser pulses, introducing deep compressive residual stresses beneath the material surface.
Unlike conventional shot peening or mechanical surface treatment methods, laser shock peening achieves strengthening without increasing surface roughness or altering component geometry and dimensional accuracy. This non-contact, highly controlled process enhances resistance to fatigue cracking, stress corrosion, and wear—resulting in longer component life, improved reliability, and reduced maintenance requirements. It is especially valuable for critical components where performance and safety margins are paramount.
With its compact footprint and modular architecture, the LSP system integrates seamlessly into research laboratories, industrial test centres, and advanced production lines. Suitable for both prototype development and full-scale manufacturing, it delivers validated, repeatable, and industry-proven surface strengthening. United Spectrum Instruments offers these advanced solutions in India as the official distributor of Bright Beams Laser, providing application expertise, system integration support, and dependable after-sales service for high-performance surface engineering applications.
Understanding Compact Laser Shock 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.
