摘要： A glass fiber according to the present invention is suitable for preventing filament breakage and suitable for being stably produced for a long term, and has a β-OH value of 0.02 mm -1 or more and less than 0.55 mm -1 . The preferred content of SO 3 is more than 0 ppm and 70 ppm or less on a mass basis. The glass fiber is preferably substantially free of As and Sb. SO 3 can be supplied to a glass raw material as, for example, a sulfuric acid salt of an alkali metal or an alkaline-earth metal.

摘要： A glass processing method comprising steps (i), (ii) carried out in the order mentioned. In step (i), a laser pulse (11) with a wavelength λ is condensed by a lens and is applied to a glass plate (12) to form an altered portion (13) at the portion, irradiated with a laser pulse (11), of the glass plate (12). In step (ii), the altered portion (13) is etched by using an etchant having an etching rate larger for the altered portion (13) than that for the glass plate (12). The laser beam used includes the following conditions: The pulse width of a laser pulse (11) ranges from 1ns to 200ns, with a wavelength λ being up to 535nm. The absorption coefficient of the glass plate (12) at a wavelength λ is up to 50cm-1. A value obtained from a lens focal distance L (mm) divided by the beam diameter D (mm) of the laser pulse (11) when entering the lens is at least 7.
