High-Repetition Lasers Change Use Cases
- High-repetition-rate lasers fire many pulses per second instead of one shot every few hours, enabling continuous, practical applications.
- This shift unlocks uses in medicine, manufacturing, and chip production by delivering repeatable precision and throughput.
Lasers Could Democratize Ion Beam Therapy
- High-repetition lasers could generate proton and ion beams for cancer therapy with greater accessibility.
- Laser-driven ion beams promise surgical precision compared to broad x-ray treatments, potentially expanding treatment availability.
Lasers Improve Additive Manufacturing Inspection
- Advanced lasers enable nondestructive internal imaging of dense additive-manufactured parts to detect hidden defects.
- That capability helps qualify parts for critical uses in aerospace, energy, and infrastructure.
