Femtosecond laser-induced periodic surface structures on fused silica: the impact of the initial substrate temperature

Popis výsledku v původním jazyce

The formation and properties of las.-induced periodic surface struct.(LIPSS)were investigated upon fs-las. irradiation of fused silica at different initial substrate temperatures,TS.For substrate heating between room temperature,TRT,and TS=1200°C,a continuous wave CO₂laser was used as the radiation source.The surface structures generated in the air environment at normal incidence with five successive fs-laser pulses(pulse duration,τ = 300 fs,laser wavelength,λ = 1025 nm,repetition frequency, frep=1kHz)were characterized by using optical microscopy,scanning electron microscopy,and 2D-Fourier transform analysis.The threshold fluence of fused silica was systematically investigated as a function of TS.It was shown that the threshold fluence for the formation of low-spatial frequency LIPSS(LSFL)decreases with increasing TS.The results reveal that the initial spatial period observed at TRT is notably increased by increasing TS,finally leading to the formation of supra-wavelength LIPSS.
