The differentiation procedure between amplified spontaneous emission and lasing phenomena

The lasing process emerges from an amplified spontaneous emission (ASE) when an optical resonator is present. The ASE is often observed during the laser emission, especially in random lasing studies. The differentiation between ASE and random lasing is difficult, particularly considering coherent and incoherent random lasing from polymeric dye-doped systems. In this article, we present the straightforward procedure of differentiation of both processes, in order to simultaneously designate the ASE and lasing emission properties and performance.
