Abstract

We present time-resolved studies of glass densification created by an acoustic phenomenon: collision of the transverse and longitudinal sound waves inside glass. Localization of the permanent denisfied region has a lateral cross section ∼ 0.4 μm and is approximately half of the wavelength of femtosecond laser pulses which were used to generate breakdown and launched shock waves inside glass. Controlled time delay between two closely spaced irradiation spots reveals dynamics and relaxation (electronic, thermal, stress) of glass after excitation. The observed phenomenon is important for femtosecond direct laser writing and recording of waveguide couplers using multiple beams.

(a) Interferometric pump-probe imaging. (b) Schematics of two pump pulses (1,2) delayed in time by Δt and separated in space by Δx. The side-spots depict location of glass densification induced by shock wave; separation between them is L.

Fig. 2
Fig. 2

Acoustically-induced densification (the darker side spots) at the end of relaxation T = ∞. Lateral phase images around the focus region of two-pulse irradiation after the end of relaxation; the darker regions are more dense. Time separation, Δt, between two pump pulses at 800 nm wavelength is shown; phase scale is from −π to π. Spatial separation between two pump pulses of energy E1 = E2 = 50 nJ was Δx = 1.0 μm (measured experimentally); L is the length between the densified side spots; polarization of pulses was linear (horizontal in the image plane). The upper irradiation site is where the first pulse arrived (darker appearance), the lower site is location of the second (delayed) pulse.

Phase at the location the middle point between the two pump pulses x = 0 (a) and at the “side spots” (b) vs separation between pulses, Δt, when Δx = 1 μm. E1 = E2 = 50 nJ. Lines are eye guidelines. Single pixel size corresponds to 35 nm on the sample. The site −L/2 (in (b)) is where the first pulse arrived, the site +L/2 is location of the second (delayed) pulse.

(a) Phase at the location the middle point x = 0 vs separation between pulses, Δx, (see, Fig. 4) for Δt = 0.2 ps and pump energies of two pulses E1 = E2 = 30; 40; 50 nJ. (b) Phase at the locations x = ±L/2 (side spots) vs separation between pulses, Δx, at pulse energy Ep = 50 nJ (two separate experiments). Lines are eye guidelines. The site −L/2 (see, Fig. 3(a)) is where the first pulse arrived, the site +L/2 is location of the second (delayed) pulse.

Phase maps of photo-acoustically induced densification at different pulse energies of 30-60 nJ at T = 5 ns and after all relaxations; Δt = 0.2 ps, Δx = 0.8 μm. Separation between side spots, L, is increasing with pulse energy, Ep. Dashed lines are alignment eye guides. Phase spans from −π to π. The site −L/2 (see, Fig. 3(a)) is where the first pulse arrived, the site +L/2 is location of the second (delayed) pulse.

Phase at the mid-point location x = 0 vs pulse energy: experiment (from Fig. 6) and linear fit by ∝ 0.15[μm](EEth) with Eth = 20 nJ; ∼ 0.15 μm is the most close distance two separate irradiation spots can be brought to. The pressure which is driving micro-explosion is proportional to the absorbed energy of the pulse of energy E. Note, both axes are logarithmic.
