A critical step in the lasing is the injection of a large amount of electrical current into the organic layers to achieve a condition called population inversion.
However, there were no significant difference between Regular and Moses contact modes in total lasing time (5.8 vs.
Random lasing is generated in this media when the pump energy is above a threshold of 7 mJ/[cm.sup.2].
A major challenge in achieving lasing this way was that light may not exist long enough in such small dimensions to be helpful.
Besides, a nanosecond laser pumped random lasing action has been achieved in the silicate oxyfluoride glass ceramics containing [Ba.sub.2]La[F.sub.7] nanocrystals.
Here, room temperature exciton-exciton lasing using solgel spin coating has been presented and theoretically analyzed for the first time, to the best of our knowledge.
The random cavity model is put forward to explain the lasing in disordered ZnO mediums, which is attributed to recurrent scattering by localized photons.
Odom's research team has found a way to integrate liquid gain materials with gold nanoparticle arrays to achieve nanoscale plasmon lasing that can be tuned dynamical, reversibly and in real time.
The lasing process is all about storing and releasing energy.
The topics include the synthesis of carbon nanotubes and graphene for photonic applications, optical gain and lasing in carbon nanotubes, carbon-nanotube based bulk solid-state lasers, electromagnetic nonlinearities in graphene, carbon nanotube solar cells, carbon nanotube-based photovoltaic and light-emitting diodes, and hybrid carbon nanotube-liquid crystal nanophotonic devices.
The contribution of the spontaneous emission to the lasing mode is calculated as the ES and GS spontaneous transitions multiplied by the spontaneous emission coupling factor [beta], assumed to be constant.
London, Feb 9 ( ANI ): Electrical engineers have built the smallest room-temperature nanolaser to date, as well as a highly efficient "thresholdless" laser that funnels all its photons into lasing, without any waste.
