Nettetlinewidth enhancement factor[31]. But when the target is a microscale moving particle, the backward scattering light acts as the feedback light, and the C value is typically smaller than 1[11]. The SMI system then operates in a weak feedback region, and the phase hysteresis can be negligible. Due to the well- Nettetlifetime in tungsten- and molybdenum-based TMDs: in MoSe 2, the coherence lifetime is determined by radiative coupling at low temperatures and by phonon-induced intravalley scattering at room temperature. In contrast, the excitons in WS 2 can be efﬁciently scattered into the energetically lower-lying intervalley dark excitonic state, cf. Fig. 1. recliner chair phoenix furniture stores
