The very intense extreme ultraviolet  XUV light of the Free electron LASer in Hamburg FLASH facility allows to investigate fundamental  processes such as direct one or few photon inner shell ionizations. A supplementary Ti:Sa 800nm  femtosecond laser system allows to perform two-color  pump-probe experiments with FLASH. Within this work  a bunch arrival measurement system has been built,  which assists these two-color pump-probe experiments  to reduce the temporal jitter of FLASH. The  diagnostic is based upon an electro-optical  detection scheme. Key feature of the diagnostic is a  150m long glass fiber pulse transport system, which allows to transport a 90fs FWHM short  800nm femtosecond laser pulse to clock the FEL  electron bunch. The timing diagnostic was part of a  series of two-color near-infrared\/XUV pump-probe  experiments and improved their temporal resolution  by more than a factor 4 from 250fs RMS or worse to  just 60fs RMS. Meanwhile the timing diagnostic  advanced to a standard diagnostic, which is  regularly utilized by pump-probe experimentalists at  FLASH.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838325798\"\u003e\u003ch3\u003eUltra-fast dynamics in photon science today.\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838325798","offer_id":39499057299549,"sku":"9783838325798","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/9deed4ee-a0f1-4590-82b3-80fa24cec9e0.jpg?v=1758346412","url":"https:\/\/shop.autorenwelt.de\/products\/temporal-jitter-reduced-two-color-pump-probe-experiments-with-a-fel-von-armin-azima","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
