DOI: 10.22184/1993-7296.FRos.2025.19.8.608.618
The paper provides the results of work on the development of single-frequency semiconductor laser modules with a wavelength of 633 nm, an external resonator and a narrow spectral linewidth of less than 1 MHz based on the fiber Bragg gratings (FBGs) generated in a single-mode fiber optic waveguide. The continuous tuning methods for the emission wavelength within the half-width of the FBG reflection contour are considered. The given laser modules are capable of generating the dynamically stable single-frequency radiation with a side mode suppression of more than 40 dB, an oscillating linewidth of less than 300 kHz, and an output optical power of more than 30 mW. The wavelength tuning of the laser module emission spectrum by the pump current is estimated to be 10 GHz (0.02 nm) within the mode interval.
