The pump source may be, for example, a MOPA laser or a diode or any other suitable source. In one embodiment, the pump pulse shape is modified such that an initial gain within the DFG is high, followed by a lower level signal for efficient conversion within the DFG. An example of such a shape is a double square pulse. Other configurations are possible as well such as a single rectangular pulse shape."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for controlling optical output of a frequency conversion device","description":"A system and method for improving conversion efficiency of a difference frequency generator (DFG) and/or for outputting a desired shape of the output signal, where the method includes providing a pump","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508839","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.
