“…Another important difference is the thermal expansion coefficient, which is six times larger for sodalime glass than for silica glass. There is also a difference in the optical band gap: about 3.2 eV for sodalime glass [39] and 7.5 eV for silica glass [6]. The properties of both glasses are summarized in Table 1.…”

“…This should be due to differences in the sound velocity in the glasses (5.93 km/s in a silica glass and 5.5 km/s in a sodalime glass), because the TrL oscillation is originated from the propagation of a pressure wave. To compare the amplitude of the TrL oscillation, we defined an oscillation amplitude (A osci ) as shown in Figure 4(c), that is, the difference of the signal intensity at [32,37], thermal expansion coefficients α [32,36], band gaps E g [6,39], refractive indices n [36], and glass transition temperatures T g [38] of silica glass and sodalime glass [32]. η (Pa·s) at 600…”

A technique to study femtosecond laser induced structural change inside glasses, the transient lens (TrL) method, is described. Because the TrL method is sensitive to the refractive index change around the photoexcited region, the time dependence of the density, pressure, and temperature changes, which accompany refractive index change, can be monitored over a broad range of timescales. In the picosecond-nanosecond time range, the pressure wave generation was observed as an oscillating TrL signal. By comparing the TrL signal with that calculated based on thermoelastic simulation, the density, pressure, and temperature changes in the photoexcited region can be estimated. In the longer time range (nanoseconds-milliseconds), the thermal diffusion process was observed. By fitting the TrL signal with that simulated based on thermal diffusion, the temporal evolution of the temperature distribution was obtained. Based on these observations, the features of femtosecond laser-induced structural change inside glasses are revealed. The advantages of the TrL method are described.
