Laser technology implemented for communication from outer space to Earth




Greetings again dear readers of this prestigious platform, it is always important to observe our surroundings in order to be able to witness the various technological applications in the development of our activities, and this, from any area of our rich history as living beings of our home Earth, of course, we must always take into account the proper balance that should exist between the use of such applications with respect for our environment because there is no use so many technological advances if in the end it is to harm our precious environment.

This time my dear friends we will be relating to a beam generation as is the Laser, and as it is of great importance in many of our activities, however, this time we will link it with the communication that is possible to obtain from outer space through the implementation of the Laser, therefore, it is important to note that this type of beam is possible to generate it from a device through an action related to quantum mechanics.

This type of beam belongs to the family of electromagnetic radiations whose injection of energy excites the atoms already present and in this way reaches a higher energy level.

This type of impressive beam is implemented to achieve communication from our planet to our outer space and vice versa, and this has been the main reason for NASA to take into account such an important feature, for example, the various missions of human beings that are sent to the planet Mars can and do use the Laser to be in communication with the stations that remain on Earth.

If we compare the use of the technology of radio systems with that of the laser beam, we can say that if a given mission to Mars requires sending a map of that planet to the stations on Earth by means of radio wave technology this can take a lapse of time of around 9 years, however, the communication technology developed through the implementation of the laser reduces this task to only 9 weeks approximately, and also the communication with the personnel or astronauts is much better with laser technology.

Therefore, laser technology has allowed astronomy to know even more about our outer space, through the laser is possible to accurately know the distance between the various bodies present in outer space with our planet, for example, the Earth and the moon, or the stars, and this due to its essential characteristics such as its rectilinear directionality (monodirectional), sense of coherence, aspects demonstrated by NASA (National Aeronautics and Space Administration) and implemented for the communication described above, then we can see one of the applications of the laser in the following figure 2.

Technological advances go towards any type of area related to our exponential development as the one we were able to analyze in a general way through the application of the laser beam in astronomy and thus allowing us to know more about our outer space and that so much passion transmits us because every time man strives more for this purpose.

Until another opportunity my dear readers, I hope to be able to count on your so important contributions and to be able to consolidate the subject raised on this occasion.
