“…Since the discovery in 1986 of a laser-like behaviour in a powder of Na 5 La 1Àx Nd x (MoO 4 ) 4 crystallites [1], laser crystal powders have been studied extensively [2][3][4][5][6][7][8][9][10][11]. Their potential applications as compact and mirrorless lasers where the coherence is not necessary or the absence of coherence is desirable, motivate the study of their optical properties and the search for new random laser materials.…”

“…Each laser mode is characterized by its own decay time (or Q-factor) and spatial distribution of the electromagnetic field. In the case of a mode localized due to disorder, the spatial distribution of the field can be altered by varying the pumping [25]. Therefore, the threshold intensity is different for different modes.…”

Synthetic opals filled with CdTe exhibit a pronounced decrease of the intensity of photoluminescence for photon energies within the photonic band-gap. However, the intensity of emission increases much faster with the level of pumping inside the photonic band-gap than outside. It is argued that this behaviour can be explained if there is stimulated emission from photonic states in the photonic bandgap, which are strongly localized due to disorder.

“…Since the pioneer work of Letokhov [1], there have been many studies on lasing in disordered media [2][3][4][5][6][7][8][9][10][11][12]. The so-called random laser is a laser based on disorder-induced scattering.…”
