Abstract: A robust broadband ASE (amplified spontaneous emission) fiber light source device outputs a light beam which is little affected by temperature and radiation. The light source device is a single-pass backward or double-pass backward architecture, and has a coolerless pump laser and temperature compensated bandpass reflector. The light source device may have a high pass filtering element disposed between the wavelength division multiplexer thereof and the optical isolator thereof, so as to compensate the effect of the temperature to the mean wavelength of the light beam. The specific band of the temperature compensated bandpass reflector which reflects the light beam, and the band which the high pass filtering element transmits the light beam are within the band which the ASE unit amplifies the light beam, and the high pass filtering element mainly absorbs the light beam outside the specific band.
