Lasers  are widely used in home appliances, medicine, industry, telecommunications and other fields. A few years ago, scientists introduced the concept of nanolasers. Their design is similar to traditional semiconductor lasers based on heterostructures that have been used for decades. The difference is that the cavity of nano lasers is very small, proportional to the wavelength of the light they emit. Since they mainly produce visible light and infrared light, their size is about one millionth of a meter. Nano lasers  have unique properties that are distinct from macro lasers. However, it is almost impossible to determine under what current the output radiation of a nanolaser is coherent; in addition, for practical applications, it is important to distinguish between two states of a nanolaser: a real laser effect with coherent output at high currents and a LED-like state with non-coherent output at low current.

Lasers are widely used in household appliances, medicine, industry, telecommunications and other fields. A few years ago, scientists introduced Nano Russell. Their design is similar to conventional semiconductor lasers based on heterostructures that have been commonly used for decades. The difference is that the cavity of the nano-lacquer is very small, which is determined by the wavelength of the light emitted by the root. Since they mainly produce visible light and infrared light, they are about one millionth of a meter in size. Nanomaterials have unique properties that are significantly different from macroscopic lasers. However, it is almost impossible to determine at what current the output radiation of the nanolaser becomes coherent. In addition, in practical applications, it is important to distinguish between two states of the nanolaser: true laser action with high current coherent output and low The LED-like state of the current incoherent output.
