“…Moreover, the irradiation dose of γ-rays is the controlling factor in determining the particle size. This is in accordance with Markushev et al (2005) who stated that with irradiation dose increasing, the prepared particle size gets smaller and the distribution of particle size is enhanced.…”

“…Powder stacks can be subject to laser-induced heating or permanent damage when subjected to repeated laser illumination, as observed in our laboratory. Intense narrow line emission due to amplified spontaneous emission is another phenomenon which can occur in stacked powder [10], but which is very unlikely in dilute suspensions due to the low subtended solid angle between individual particles.…”

“…Besides the many experimental papers, also many theoretical papers appeared that tried to disentangle the physics behind the random lasers. [4,6,25,32,64,68,72,89,96] On one hand Cao et al [25], as well as Sebbah and Vanneste [89] and Apalkov et al [6], attribute the spikes to local cavities for light, that are formed by multiple scattering. We will refer to this explanation as the "local-mode" model.…”

“…In the past few years a debate on the origin of the narrow spectral features (spikes) that occur in the emission spectrum of some random lasers has started [4,6,25,32,64,68,72,89,96]. On one hand Cao et al [25], as well as Sebbah and Vanneste [89] and Apalkov et al [6], attribute the spikes to local cavities (local modes, LM) for light, which are formed by multiple scattering.…”
