Note: In gas nano lasers, gas flows inside the resonator. When the gas flows, it passes through two ͺelectrodes, one of which has a positive charge and the other has a negative charge. The electrons that flow between the electrodes pump the electrons of the flowing gas atoms to high energy levels. Various gases can be used as the active medium in nanolasers. Gas nanolasers include carbon nanolasers. Dioxide, carbon monoxide, helium-neon, helium-cadmium, argon, grypton, nitrogen molecules, exmir, copper vapor and gold vapor are examples of these nano lasers.
A gas nanolaser is a device that emits light waves in the form of very narrow parallel beams that have a specific wavelength. Gas nanolasers that use electron impact to produce excited ions, which are active nanolaser devices. The main part of ion nano lasers are plasma tubes. The current flow in the tube can be more than 10 nm. Gas nanolasers all share a pump source and the gas species are spontaneously excited either directly, by collision with electrons, or indirectly, by collision with other gases. They cover light. However, the spectrum is not covered continuously. Gas nanolasers emit very narrow spectral lines. The most common gas nano lasers (from UV to far ultraviolet).
Among the different types of gas nano lasers, carbon gas nano lasers, having the highest average power among gas lasers, are widely used in various cases due to this wide application of high efficiency. (nanolaser) is a laser that on the scale of nano dimensions, these tiny lasers can be quickly modulated and together with the small footprint, make them ideal candidates for optical computing on a chip . The intense optical fields of such lasers also enable the amplification effect in nonlinear optics or surface-enhanced scattering (Raman Raman) , thus paving the way for integrated nanophotonic circuits , generally nanolaser enhancement or amplification . It is a process in which the environment transfers part of its energy to the emitted electromagnetic radiation , and as a result, the optical power increases. 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 :
In gas nanolasers, gas flows inside the resonator. When the gas flows, it passes through two ͺelectrodes, one of which has a positive charge and the other has a negative charge. The electrons that flow between the electrodes pump the electrons of the flowing gas atoms to high energy levels. Various gases can be used as the active medium in nanolasers. Gas nanolasers include carbon nanolasers. Dioxide, carbon monoxide, helium-neon, helium-cadmium, argon, grypton, nitrogen molecules, exmir, copper vapor and gold vapor are examples of these nano lasers.
