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

In some nano-lasers, liquid is used as the active medium. Due to the fact that liquids are denser than gases, liquid nano-lasers have the advantage that they cool more easily when they flow. Colored nanosacres are an example of such lasers. Note that colored nanosacres 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 other laser. The beam produced by these nano-lasers can range in wavelength range from 50 nm to 655 nm.

The laser is no different in nature from ordinary light, and the physical properties of the laser distinguish it from light generated by other sources. In liquid-colored nanocars  lasers  , a solution of complex materials is used as the active medium. Dyes are large organic molecules that have a molecular weight of several hundred. Therefore, the active medium is liquid. In general  (nano-laser) is a laser that at the nanoscale  ,  these tiny lasers can be quickly modified and, along with  small  footprints , make them ideal candidates for optical computations  on the chip  . The intense light fields of such a laser also enable the effect of amplification on nonlinear  or scattered optics (Raman) with enhanced surface   area. And so pave the way for circuits nano-photonic integrated pave , generally Nano Laser nano lasers  to increase  or  strengthen  the process by which the environment is part of their energy to electromagnetic radiation  emitted by transfer  and thus the optical power increases. This is the basic principle of all lasers . Quantitatively,  increasing  measurement is the ability of a laser medium  to increase optical power.

Conclusion : 

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