Note: Normally, the laser beam is continuously exited from the optical chamber of the nano laser, the output power of cw nano lasers has a wide range. Liquid and ion nano lasers are examples of continuum lasers. This range includes milliwatts like nano lasers for optical communication to several microwatts (3 to 5 microwatts) like nano lasers used in military industries. 

The output of the nano laser is a type of light that is placed in different parts of the electromagnetic wave spectrum according to the active environment of the nano laser. Wavelength is one of the most important properties of waves, which has an inverse relationship with energy. Therefore, different waves can be displayed as a spectrum of electromagnetic waves.


Laser light is called pure light because it has the same wavelength. The laser light waves move at the same time and are in phase, which means that the peak of each wave is the same as the peak of another wave, because of these characteristics, it is called coherent laser light. Because of the same wavelength or frequency. , the laser light is not decomposed when passing through the prism and exits in the form of a small beam. (as it is inserted) Another feature of laser light is its directionality. If laser light is not absorbed in the environment, it can travel long distances without much change in its divergence. The brilliance or brightness of laser light is millions of times greater than other sources such as the sun. The reason for this is that the laser light is coherent and moves in one direction. Because it is possible to control the input energy in the laser, and for this reason the output energy changes as well, for this reason, if the laser excitation happens with small pulses, the laser production is done with small pulses. have the same color and are so-called monochromatic.


Conclusion : 

Normally, the laser beam is continuously exited from the optical chamber of the nano laser, the output power of cw nano lasers is wide range.
