Fused Silica Glass

Deep wet etching for polished fused silica glass in HF solutions was investigated to manufacture quartz pendulous reed with better surface quality and higher size precision. It is widely believed that etching rate was mostly decided by the temperature and concentration of HF solutions. But, in the beginning it was found difficult to control the uniformity of etching depth when the glass was etched for 0.3 ~ 0.5 mm each side. Now, it is detected with help from new designed etching machine that depth of 0.5mm or more can be achieved very easily. And the uniformity about ±0.002 mm would also be realized easily by keeping the sample glass at same depth and moving all the time in HF solution with the temperature and concentration are 45°C and 40% HF

Using the coherence theory of non-stationary fields and the method of Fourier transform, the spectral properties of spatially and spectrally partially coherent Gaussian Schell-model pulsed (GSMP) beams in fused-silica glass medium are studied and analyzed numerically. It is shown that the spectral shift takes place, which depends on the position of the field point, spatial correlation length, temporal coherence length and dispersive property of medium, as GSMP beams propagate in fused-silica glass medium. The on-axis spectrum is blue-shifted, and the relative spectral shift increases with increasing propagation distance, and decreases as the spatial correlation length and temporal coherence length increases, and then approaches an asymptotic value. The dispersive property of medium plays an important role in the spectral properties of spatially and spectrally partially coherent beams.
