Elastic and Thermal Dynamics in Femtosecond Laser-Induced Structural Change Inside Glasses Studied by the Transient Lens Method
(a) TrL images at different time-delays and mm. The pump energy was 0.25 μJ/pulse. (b) The TrL signal measured under the same conditions as for (a). (c) The TrL signal simulated using pressure wave propagation.
