This paper investigates damage free ultrasound generation on Carbon Fiber Reinforced Composites using a range of different lasers: TEA CO2 (10.6mum), Nd:YAG (1064nm) and a XeCl excimer laser (308nm). It is essential that no damage is caused to the components and this restricts generation to the thermoelastic regime, where it is due to rapid thermal expansion. For this reason, the laser damage thresholds of the samples are presented and compared.
