(Industrial Liquid Nano-Lasers (Liquid Nano-Lasers

Tip: To understand the concept of  liquid nano lasers   , imagine a nano laser pointer that changes color easily by changing the liquid inside it instead of needing a different laser pointer for each desired color.

In some nano lasers, liquid is used as an active medium. Considering that liquids are denser than gases, liquid nanolasers have the advantage that they can be cooled more easily by flowing. Color nano lasers are an example of these lasers. Note that color nano lasers are dissolved in a solvent medium such as alcohol, ethylene glycol or water. Solutions are homogeneous mixtures. Solutions are usually classified according to their physical state. In these lasers, the output source is a flash lamp or another laser. The beam produced by these nano lasers can include a wavelength ranging from 570 nm to 655 nm.

In terms of its nature, the laser is no different from normal light, and the physical properties of the laser distinguish it from the lights created from other sources. In colored liquid nano  lasers  , a solution of complex materials is used as an active medium. Colors are large organic molecules whose molecular weight reaches several hundreds. Therefore, the active medium is liquid. In general  , (nanolaser) is a laser that at the nanoscale  ,  these tiny lasers can be quickly modulated and along with the  small  footprint,  make  them ideal candidates for optical computing on a chip .  The intense optical fields of such a laser also enable the amplification effect in nonlinear optics  or scattering (Raman) with increased surface area  .And  thus paves the way for integrated nano photonic circuits , in general Nano Laser Nano laser   enhancement  is  a process in which the medium  transfers part of its energy to the emitted electromagnetic radiation  , resulting in an increase in optical power. This is the basic principle of all lasers . Quantitatively,  gain is  a measure of the ability of a laser medium  to increase optical power.

Conclusion :

To understand the concept of  liquid nanolasers   , imagine a nanolaser pointer that changes color easily by changing the liquid inside it, instead of needing a different laser pointer for each desired color.
