  • Title: Noise reduction of supercontinua via optical feedback.
    Author: Brauckmann N, Kues M, Gross P, Fallnich C.
    Journal: Opt Express; 2011 Aug 01; 19(16):14763-78. PubMed ID: 21934838.
    Abstract:
    The impact of delayed optical feedback on the supercontinuum noise properties is investigated numerically and experimentally. The supercontinuum is generated by coupling femtosecond laser pulses into a microstructured fiber within a ring resonator, which introduces the optical feedback. The power noise and spectral amplitude noise properties of this feedback system are numerically and experimentally compared with single-pass supercontinuum generation. In a demonstrative experiment via optical feedback the power noise could be reduced by 15 dB and the spectral amplitude noise could be reduced by up to 28 dB.
