The fiber length of superfluorescent fiber source and the pumping power of semiconductor laser (LD) were optimized in the temperature range of -45 ℃ ~ 70 ℃. The optimization method of LD pumping power by interpolation was proposed. Based on fiber length optimization, pumping power is optimized efficiently and accurately, and the average wavelength stability of the light source is improved. The optimized light source has an average wavelength variation of 0.67 × 10-6 / ° C in the temperature range of -45 ° C to 70 ° C and a output stability of 0.37%.
