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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Femtosecond ultraviolet laser","description":"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","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9660412","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
