| Abstract Scope |
Lasers are more and more used to shape or functionalize glasses used for optical applications. They are used to cut, write waveguides, create nanograttings, etc… This open a very large play ground to design and produce future optical devices. However what really happen to the glass itself is still not fully understood and controlled. Submitted to extreme conditions the structure of glass evolves and keeps in memory its formation conditions. Raman and Brillouin spectroscopy and the luminescence of rare Earth elements as Eu and Nd allow us to read this memory.
It will be first explain how reliable multi-parameters calibration curves can be obtained to correlate the observations with physical parameters as cooling rate, maximal pressure, residual stress. Secondly, it will be shown a large number of examples how these different spectroscopic methods offer a versatile and efficient way to screen the link between laser parameters and the final object. |
