"Coherent and spectral beam combining in thulium doped fiber laser and amplifier array"@en . "0"^^ . "2015-04-23+02:00"^^ . . "We will investigate the ways of increasing radiance of thulium doped fiber lasers using spectral and coherent beam combining techniques. 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."@en .
