Abstract
A method and system for generating femtosecond (fs) ultraviolet (UV) laser pulses enables stabile, robust, and optically efficient generation of third harmonic fs laser pulses using periodically-poled quasi-phase-matched crystals. The crystals have different numbers of periodically poled crystalline layers that enable a long conversion length without back-conversion and without a special phase-matching direction. The fs UV laser may have a high conversion efficiency and may be suitable for high power operation.
