  • Patent number: 11719993
    Abstract: The disclosed laser system is configured with a laser source outputting light at a fundamental frequency. The output light is incident on a frequency converter operative to convert the fundamental frequency to a higher harmonic including at least one frequency converting stage. The frequency converter is based on a SrB4O7 (SBO) or PbB4O7 (PBO) nonlinear crystal configured with a plurality of domains. The domains have periodically alternating polarity of the crystal axis enabling a QPM use and formed with each with highly parallel walls which deviate from one another less than 1 micron over a 10 mm distance.
    Type: Grant
    Filed: December 18, 2019
    Date of Patent: August 8, 2023
    Assignee: IPG PHOTONICS CORPORATION
