Laser-induced ultrasound for applications in metrology
| Type of Publication: | Journal article |
| Author: | Krauß, Nico; Nast, Almut; Heinecke, Dirk C.; Dekorsy, Thomas |
| Year of publication: | 2015 |
| Published in: | Laser + Photonics ; 10 (2015), 1. - pp. 74-76. - ISSN 1865-6633 |
| Summary: |
The optical generation and detection of high-frequency ultrasound by employing ultrashort laser pulses enables the measurement of characteristic material parameters. A high-speed pump-probe system based on two synchronised Ti:Sapphire lasers is used to determine the thickness of multilayer films with sub-nm depth resolution at kHz scan rates. Due to a fibre-coupled delivery, the measurement system can also be applied in harsh environments and to the inspection of large and complex samples.
