Development of a high-average-power small-scale Nd:YAG laser system for infrastructure inspection
- 1. Japan Atomic Energy Agency, Kansai Photon Science Institute, Project Promotion Office, Kizugawa, Kyoto (Japan)
Description
An outdoor-use laser system to improve the performances of existing tunnel inspection techniques is studied. One of the typical concepts is that the blow by hammer in routine hammering test is replaced by the laser pulse irradiation. This new laser system is required to provide high average output power (5 J, 50 Hz, 15 ns) with a compact geometry enough to mount on the inspection vehicle (4.2 m x 0.8 m). Dramatic speed-up of the inspection is expected by the combination of this new laser system and a laser scanning frequency measurement system. (author)
