Wavelength stabilization of a 980-nm semiconductor laser module stabilized with high-power uncooled dual FBG

摘要 An optimized dual fiber Bragg grating （FBG） is proposed for 980-nm semiconductor lasers without thermoelectric coolers to restrict temperature-induced wavelength shift.The mathematical model of the temperature-induced wavelength shift of the laser with the dual FBG is built using the external cavity feedback rate equations.The external cavity parameters are optimized for achieving the stability mode-locking laser output.The spectral characteristics of the dual FBG stabilized laser are measured to range from 0 to 70 °C.The side mode suppression ratio （SMSR） is more than 45 dB,while the full-width at half-maximum （FWHM） is less than 1 nm.The peak wavelength shift is less than 0.1 nm.The dual FBG wavelength shift proportional coefficient is between 0.1086 and 0.4342.
