Previous record pulse energies\u003cbr\u003e\nobtained directly from an oscillator in ambient atmosphere were below 2 _J. This thesis describes a newly developed thin-disk laser oscillator with an increased\u003cbr\u003e\nround-trip gain by employing a self-imaging active multipass geometry. The generation\u003cbr\u003e\nof high energy subpicosecond pulses with a pulse energy of up to 25.9 _J at a\u003cbr\u003e\npulse duration of 928 fs, while operated in ambient atmosphere, could be demonstrated.\u003cbr\u003e\nStable single-pulse operation has been obtained with an average output\u003cbr\u003e\npower in excess of 76W at a repetition rate of 2.93MHz. Self starting passive modelocking\u003cbr\u003e\nwas accomplished using a semiconductor saturable absorber mirror (SESAM)\u003cbr\u003e\nwith a modulation depth of 3.5%%. The laser was operated at output-coupling rates of\u003cbr\u003e\nup to 78%%.\u003c\/p\u003e","brand":"Joerg Neuhaus","offers":[{"title":"Paperback","offer_id":44310338142369,"sku":"9781409269854","price":33.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0462\/1120\/3233\/files\/1q68vpky-front-shortedge-384.jpg?v=1748303884","url":"https:\/\/bookswholesale.myshopify.com\/products\/mode-locking-of-an-active-multipass-geometry","provider":"BooksWholesale","version":"1.0","type":"link"}
