We propose to employ the\u00a0Fox-Smith resonator made of single mode large mode area fibers \u00a0for self-organized coherent beam combining in spectral region of 2000 nm. Further, we propose new scheme of spectral beam combining. The beam is spectrally decomposed to four beamlets on a diffraction grating. After individual amplification in double-pass thulium doped fiber amplifiers, the beamlets are assembled on the same grating. The proposed techniques of coherent and spectral beam combining will allow to achieve the power of 120 W in diffraction limited beam at a wavelength of 2000 nm.<\/p>\n","protected":false},"template":"","vyzkumne_tymy":[57],"acf":[],"_links":{"self":[{"href":"https:\/\/www.ufe.cz\/en\/wp-json\/wp\/v2\/grantove_projekty\/21736"}],"collection":[{"href":"https:\/\/www.ufe.cz\/en\/wp-json\/wp\/v2\/grantove_projekty"}],"about":[{"href":"https:\/\/www.ufe.cz\/en\/wp-json\/wp\/v2\/types\/grantove_projekty"}],"wp:attachment":[{"href":"https:\/\/www.ufe.cz\/en\/wp-json\/wp\/v2\/media?parent=21736"}],"wp:term":[{"taxonomy":"vyzkumne_tymy","embeddable":true,"href":"https:\/\/www.ufe.cz\/en\/wp-json\/wp\/v2\/vyzkumne_tymy?post=21736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
