WebJan 29, 2024 · In this paper, we demonstrate a narrow-linewidth tunable fiber laser based on laser-induced graphene (LIG) paper-heated fiber Bragg grating (FBG) with low voltage. A linewidth of less than 600 Hz is achieved by the combination of a piece of unpumped Er-doped fiber and an FBG. WebGratings are used to split incident light into several beams spread over multiple directions. They are used alongside spectrometers to measure wavelength intensity over a specific portion of the electromagnetic spectrum. This provides information about the sample by producing a spectral fingerprint.
