Industrial Nano Laser (Femtosecond) or Liquid

Note: Femtosecond nanolaser When the laser wave break interval is about 5 femtoseconds, it is called a femtosecond nanolaser. Note that each femtosecond (fs) is equal to 10-15 seconds. Some fluid lasers are examples of these lasers.

Femtosecond nanolasers  are devices that emit light waves in the form of very narrow parallel beams of a specific wavelength.  Gas nanolasers ,  which  use    the impact of electrons to produce excited ions, are the active devices of nanolasers. The main part of ion nanolasers are plasma tubes.  The current flow in the tube can be more than 10 nanometers. Gas nanolasers all share a common pump source, and  the gas species are excited either directly, by collision with electrons, or indirectly, by collision with other gases. Femtosecond nanolasers  cover the optical spectrum from the ultraviolet to the far infrared.  However, the spectrum is not covered continuously.  Femtosecond nanolasers  emit very narrow spectral lines.  The most common gas nanolasers (from UV to far ultraviolet) are

Among the various types  of femtosecond nanolasers , carbon nanolasers have the highest average power among gas lasers, which is why they are widely used in various applications. (Nanolasers) are lasers that can be rapidly modulated at the nanoscale  ,  and combined with their  small  footprint , make them ideal candidates for  on-chip  optical computing .  The intense optical fields of such lasers also  enable the enhancement effect in nonlinear optics  or Raman scattering with increased surface area  ,  thus paving the way for integrated nanophotonic circuits . In general, nanolaser  enhancement  or  amplification  is the process in which a 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,  enhancement is  a measure of the ability of a laser medium  to increase optical power.

Conclusion :

Femtosecond nanolaser When the laser wave decay interval is about 5 femtoseconds, it is called a femtosecond nanolaser. Note that each femtosecond (fs) is equal to 10-15 seconds. Some liquid lasers are examples of these lasers.
