Laser Technology: Principles, Properties, and Applications

LASER = Light Amplification by Stimulated Emission of Radiation

A laser is actually an oscillator rather than a simple amplifier. The difference is that an oscillator has positive feedback in addition to the amplifier.

Light is understood in a general sense: electromagnetic radiation with a wavelength around 1 μm. Thus, one can have infrared, visible, or ultraviolet lasers.
The atomic medium with population inversion used in the laser is called the active medium. The positive optical feedback is obtained

Two Simultaneous Events in Relativity

There will be two simultaneous events since there will be a dilation of mass, time, and length, ranging from relativistically. The only condition to produce this phenomenon is that the speed of the moving observer must be close to the speed of light.

Relativistic and Classical Physical Theories

Two physical theories are briefly described: relativistic and classical. The results are as follows:

  • The corpuscular theory of light, explained through the Compton effect,

Celestial Mechanics: Kepler’s Laws

Johannes Kepler, a German astronomer and mathematician, established the mathematical laws describing the motion of celestial bodies. He determined that planets move in elliptical orbits, not circular ones, around the sun. These are known as Kepler’s Laws:

  • 1st Law: Planets move in elliptical orbits with the sun at one focus.
  • 2nd Law: A line connecting a planet to the sun sweeps out equal areas during equal intervals of time.
  • 3rd Law: The square of a planet’s orbital

Low Voltage Distribution Networks: Aerial and Underground

Posted by on Jan 19, 2025 in Physics | 0 comments

The distribution network in Low Voltage (LV) begins at processing centers where Medium Voltage (MV) is passed to LV. This network is regulated by Article 8 of the Electrical Regulations for LV and is defined as a set of conductors that, assuming a processing center, runs along the entire supply area of influence.

Types of LV Distribution Networks

LV distribution networks can be one of two types:

  • Aerial Network
  • Underground Network

Aerial Networks

In aerial networks, conductors can be woven or braided and

Cosmology and the Expanding Universe

Cosmology, a branch of astronomy, studies the structure, origins, and development of the entire universe. Astronomy is the science that studies the stars and components of the universe. Astrophysics studies the composition, structure, and evolution of celestial objects.

Cosmology describes the universe through the application of mathematical models, which are sets of equations used to describe physical systems. These models help to further study the properties
