Optoelectronic feedback (OEF) system plays an important role in nonlinear dynamics because of low-cost and easy to generate dynamical states, including regular pulsing (RP), quasi-pulsing (QP), and chaotic pulsing (CP). However, the non-ignored noise naturally generated by delay-loop frequency in the dynamical states is the most important problem to be solved. In this paper, we focused on the generation of RP states and also on the improvement of the noise reduction in the RP states by utilizing the double-delay system. The double-delay system is built up by optical feedback (OF) and OEF systems. When adjusting four controllable parameters of OEF delay time, OEF feedback strength, OF delay time, and OF feedback strength, more complex dynamics are obtained compared to those observed in individual OF and OEF system. Moreover, noise reduction of the RP states caused by the mixing of delay loop frequencies in double-delay scheme is realized by applying an additional OF delay loop to the already-generated RP states by OEF scheme. To explore the quality of the generated RP states, the measurements of amplitude variation in time series and the single-side band phase noise in frequency domain are examined. As a result, effective noise reduction in RP states is achieved while applying a weak OF feedback strength and a short OF delay time. Furthermore, no common factor in these two delays is necessary to observe stabilized RPs and the amplitude variation down to 0 which is equal to 100 percentage noise reduction is achieved while fine-tuning the controllable parameters carefully.
