The active medium in a laser is the material that generates light amplification through stimulated emission of radiation. This material typically consists of atoms or molecules that can be excited by an external energy source to emit coherent light. Common examples of active mediums are gases (such as helium and neon), solid-state materials (like crystals or glass), and semiconductors (such as gallium arsenide).

Is active material and gain medium in lasers the same?

No, they are not the same. The active material in a laser is the substance that emits the light when stimulated, while the gain medium is the part of the laser that amplifies the light passing through it. The gain medium is typically made of the active material along with other components to enhance the laser's performance.


What are the conditions for laser?

The conditions for laser operation include having an active medium to generate light amplification by stimulated emission of radiation, a mechanism for pumping energy into the active medium, and mirrors to create optical feedback to sustain laser oscillation.


What is the basic components for a basic laser?

The basic components of a laser include an energy source to pump the laser medium, a laser medium that amplifies light, and optical components like mirrors to create feedback and produce a coherent beam of light. Additionally, a laser typically has a mechanism to control the output such as a cavity to contain the medium and shape the beam.


Difference between he-ne laser and ruby laser?

1.he-ne laser is gaseous state. Ruby is solid state laser. 2.he-ne laser requires electrical pumping. ruby laser requires optical pumping. 3.he-ne laser has 4 energy levels. ruby has 3 energy level. 4.he-ne laser gives continuous output. ruby laser gives output in form of pulse 5. he-ne laser is cheaper


What is a gain medium in lasers?

A gain medium is a material within a laser system that amplifies light through stimulated emission to produce coherent light. It is responsible for providing the necessary conditions for the laser beam generation by allowing the laser gain to exceed the losses in the laser cavity. The gain medium typically consists of atoms, ions, or molecules that can absorb and emit light at specific wavelengths.

What is semiconductor laser?

A semiconductor laser is a type of laser which utilizes a semiconductor as its Photon source, rather than a gas (Argon, CO2, Etc...) laser which uses inert gas as an active medium. Many physicists and engineers consider a semiconductor laser a type of "Solid-State" or "Two-State" LASER.


What is the role of He gas in He Ne laser?

Helium gas serves as the active medium in a He-Ne laser. It provides population inversion between energy levels, allowing for laser action. The helium gas helps to excited the neon atoms to produce laser light at a wavelength of 632.8 nm.

How fiber-laser works?

How it works.... a laser consist of a source of energy called a pump, a material called the active medium, and properly aligned mirrors called resonators. When the laser is operated, the pump provides energy to the active medium to enable it to shift to an excited state. Spontaneous emission does not happen simultaneously for all the atoms in the active medium. When an atom undergoes spontaneous emission, the ligth it emits stimulates neighboring atom to emit light that, in turn, stimulates another neighboring atom to emit ligth. Since ligth does not disappear when it stimulates an atom, more and more light becomes available to stimulate more atoms as they move through the material. With mirrors on opposite side of the active, light keeps going back and fort , becoming more and more intense every time it passes through the medium. This intensification of light is called light amplification. Since it occurs due to stimulated emission of radiation , the process is called light amplification through stimulated emission of radiation or LASER.

Is a diode laser a nd. yag laser?

No, a diode laser and an Nd:YAG laser are two different types of lasers. A diode laser uses a diode as the laser medium and is commonly used for various applications such as hair removal and skin treatments. On the other hand, an Nd:YAG laser uses neodymium-doped yttrium aluminum garnet as the laser medium and is often used for medical and cosmetic procedures, as well as in industrial applications.
