We investigate intensity fluctuations of a weakly scattering optofluidic random laser having coherent and incoherent emission fractions. The part comprises spikes, whereas the forms broad pedestal in spectra. Evaluating fractional ratio parts emission, replica symmetry breaking phase transition is observed independently both intensity. Also, component has higher non-zero correlation values compared to those part, implying larger contribution mode coupling. Moreover, survival function analysis reveals significant on determining decay profile lasing
