Abstract
An optical component made of synthetic quartz glass includes a glass structure substantially free of oxygen defect sites and having a hydrogen content of 0.1×10to 1.0×10molecules/cm, an SiH group content of less than 2×10molecules/cm, a hydroxyl group content of 0.1 to 100 wt. ppm, and an Active temperature of less than 1070° C. The optical component undergoes a laser-induced change in the refractive index in response to irradiation by a radiation with a wavelength of 193 nm using 5×10pulses with a pulse width of 125 ns and a respective energy density of 500 μJ/cmat a pulse repetition frequency of 2000 Hz. The change totals a first measured value Mwhen measured using the applied wavelength of 193 nm and a second measured value Mwhen measured using a measured wavelength of 633 nm. The ratio M/Mis less than 1.7.
