The short-pulse light source (1) controls a voltage pulse half-width (Thalf), which is a pulse width of the drive voltage pulse (DJw), by setting a pulse width (Ws) of a set pulse (SLs), thereby adjusting a ratio between the specific peak (APK) and the specific slope (ASP)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Short-pulse light source, laser light emitting method, optical device, optical disk device, and light pickup","description":"The present invention can control output of pulses from a semiconductor laser.In the present invention, a short-pulse light source (1) applies a laser drive voltage (DJ) having a pulse-shaped drive vo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8467283","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.
