Abstract
Apparatus for generating ultraviolet (UV) pulsed laser-radiation for material-processing includes a laser-source providing infrared (IR) pulsed laser-radiation and a frequency-conversion module. A lithium tetraborate (Li2B4O7) crystal located within the frequency-conversion module converts the IR pulsed laser-radiation to UV pulsed laser-radiation by non-linear harmonic generation. The frequency-conversion module is an airtight enclosure that may be evacuated or contain a dry gas. A flexible optical fiber-assembly transports the IR pulsed laser-radiation from the laser-source to the frequency-conversion module.
