Note: In gas nano-lasers, gas flows inside the resonator. When gas flows, it passes through two electrodes, one with a positive charge and the other with a negative charge. The electrons flowing between the electrodes pump the electrons of the flowing gas atoms to high energy levels. Different gases can be used as active medium in nano-lasers. Nano-laser gases include carbon nano-lasers. Dioxide, carbon monoxide, helium ‐ neon, helium ‐ cadmium, argon, krypton, nitrogen molecules, excimer, copper vapor and gold vapor are examples of these nano-lasers.
A gas nano-laser is a device that emits a wave of light in the form of very thin parallel beams of a specific wavelength. Gas nano- lasers that use the effect of electrons to produce excited ions, which are the active devices of nano-lasers. The main component of ion nano-lasers are plasma tubes. The flow rate in the tube can be more than 10 nanometers. Gas nano-lasers all share the same pump source, and gaseous species are either directly excited by contact with electrons or indirectly by contact with other gases. Nano- laser gases range from ultraviolet to infrared They cover the light. However, the spectrum is not constantly covered. Gas nano-lasers emit very narrow spectral lines. The most common are gas nano-lasers (UV to UV).
Among different types of gas nano-lasers, carbon dioxide nano-lasers with the highest average power among gas lasers are widely used in various applications due to this wide application of high efficiency. (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 lasers also enable the amplifying effect on nonlinear optics or scattering (Raman) with enhanced surface area, thus paving the way for integrated nano photonic circuits , generally nano particles increasingor amplifying to increase optical power.
