    Abstract: PROBLEM TO BE SOLVED: To provide an F-doped quartz glass material used in the lithographic application operating at a shorter wavelength than about 300 nm, which shows a lower polarization-induced birefringence or preferably, does not show the polarization-induced birefringence substantially even after being subjected to 10 million pulses of linearly polarized pulsed laser beam at 157 nm having a fluence of 250 μJ×cm -2 ×pulse -1 and a pulse length of 30 ns. SOLUTION: The F-doped synthetic quartz glass material contains, by weight, less than 50 ppm of Cl, less than 50 ppb of Na, less than 50 ppb in total of transition metals, and 0.1-5,000 ppm of fluorine.
