 note = {We have developed the flash lamp pumped Nd:YAG laser with 2 J, 50 Hz for the laser hammering test that inspects a tunnel lining concrete. A simple and compact laser system that thermal lens effect was compensated by an adjustment of image tube had a high impact resistance and stability. As the result of the outdoor practical-test in 1.5 month, this laser system was shown to be available for a maintenance-free operation.},
