How, then, can we recognize lasing? The key properties arise from light amplification by stimulated emission of radiation in a resonator (), leading to spectral and temporal coherence of the ...

When capital gains earned on the sale of securities are reinvested to buy new shares, the investor is believed to have carried out tax harvesting.

Moreover, by introducing a periodic potential into the system and balancing gain and loss, it is possible to reduce the lasing threshold and overcome the limitations of traditional plasmonic ...

As in a conventional laser cavity, the idea is that losses can be overcome by adding some form of optical gain, thus producing stimulated amplification and lasing that is then outcoupled from the ...
