The luminescence of pure crystalline a-quartz is studied under pulsed ArF laser excitation. The luminescence parameters obtained correspond well with those of self-trapped excitons (STEs) in a-quartz, indicating that the excitation process is twophoton. The efficiency of two-photon excitation is of
