Laser damage and ablation with femtosecond pulses: recent measurements and applications
Résumé
The metrology of laser damage is essential for the development of intense laser chains and their applications, especially in micromachining. We first present a test bench able to accurately measure the damage and ablation behaviour of optical materials and components irradiated by femtosecond lasers (< 15 fs - 5 ps). We further illustrate the interest of our measurements through examples related to laser technology and engineering, and also fundamental knowledge of laser-matter interaction.
