Paper Title:
Absolute Single-Mode Lamb Wave Generation by Laser in a Thin Plate
  Abstract

We present a laser-ultrasonic technique to generate the lowest symmetric ( ) Lamb wave in a thin plate. Using this special technique, in which two symmetric laser beams quasi-simultaneously hit at the same point on both sides of the plate, we absolutely suppress anti-symmetric Lamb wave modes. This technique is applicable to any situation that requires symmetric Lamb wave mode operation and does not need additional contacts or special equipments.
