The spectrum of such a grating contains asymmetric side resonances located predominantly in the long-wavelength region of the spectrum. At the wavelength of one of the dips separating these resonances, single-frequency lasing with a linewidth of \u223c1 kHz is observed at a maximum output power of 0.74 mW obtained at a pump power of 540 mW. The power and spectral characteristics of the presented laser are comparable with those of a regular laser with distributed feedback.<\/div>\n<div><\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> fibre lasers, fibre Bragg grating, single-frequency lasing<\/div>\n<div><\/div>\n<div><b>Received:<\/b> 16.09.2022<br \/>\n<b>Revised:<\/b> 24.10.2022<br \/>\n<b>Accepted:<\/b> 24.10.2022<\/div>\n","protected":false},"excerpt":{"rendered":"<p>M.
