研究目的
Investigating the effect of focused femtosecond laser pulses on antimony silicate glass in thermal and athermal regimes.
研究成果
The introduction of 25% (molar content) Sb2O3 into the silicate matrix suppresses the formation of birefringence characteristic of nanogratings. Under specific laser parameters, weak birefringence with slow axis parallel to the polarization plane of the laser beam arises, accompanied by precipitation of crystalline phases. The mechanism of this birefringence requires further study.
研究不足
The study was limited to binary antimony silicate glass and did not explore the effects on more complex glass compositions. The range of laser parameters was also limited, and higher pulse energies were not covered.
1：Experimental Design and Method Selection:
The study involved the use of focused femtosecond laser pulses to modify antimony silicate glass. The laser parameters were varied to study the effects in different regimes.
2：Sample Selection and Data Sources:
Binary antimony silicate glass with nominal composition 25Sb2O3–75SiO2 % (molar content) was synthesized and used.
3：List of Experimental Equipment and Materials:
A femtosecond regenerative amplifier (Pharos SP, Light Conversion Ltd) with working wavelength 1030 nm was used. The glass was synthesized using amorphous SiO2 and Sb2O
4：Experimental Procedures and Operational Workflow:
The laser beam was focused inside the glass sample using an Olympus 50x objective. The number of pulses, energy, and repetition frequency were varied.
5：Data Analysis Methods:
The morphology and birefringence of the modified zones were analyzed using optical microscopy and Raman scattering spectroscopy.
