Abstract :
The nonlinear interaction between glasses and ultrashort laser pulses called the multiphoton effect was studied. The change of glass structures caused by this effect leads to internal modification, on a nano-scale, inside glasses, such as densification, valence reduction of rare-earth ions, single crystal precipitation and so on. In summary, the nonlinear effect of glasses for photonic materials is introduced from the view point of device application.
