First of all, it is important to know the definition of laser:
LASER - LIGHT AMPLIFICATION BY STIMULATED EMISSION OF RADIATION
A laser functions as an oscillator or a resonance of light (inside the laser device) in the sense that the radiation is produced by the power supply which cause an active lasing medium to emit electrons at a certain frequency (thereby giving a light). These electrons are emitted inside the device and reflected back and forth by a mirror numerous number of times. The in turn excite other electrons, thereby emitting photos (light) from the lasing medium. Therefore one action results in further action. Thus completing the definition - emission is for light in form photons due to the electrons which are a form of radiation and they are amplified inside. This produces a beam that is parralel in nature and is emitted out eventually through the small slit (source). By exciting electrons with different energies, you can emit light at different wavelengths, thereby different colours.
Hope this helps.
All the best,
What else can I help you with?
What does a laser produce?
A laser is a device to produce an intense monochromatic beam of coherent light.
What will produce more widely spaced fringes of light when passed through a diffraction grating light from a red laser or green laser?
Light from a red laser will produce more widely spaced fringes of light when passed through a diffraction grating compared to light from a green laser. This is because red light has a longer wavelength than green light, causing it to diffract more.
What is a device that produce coherent light?
The name of the device that produces coherent light is LASER.
Which device used to produce high level of light energy?
A laser.
Is laser produce heat?
Yes, lasers can produce heat as they typically generate intense beams of focused light energy. This light energy can be absorbed by a surface, resulting in heating of the material. This property is often utilized in various laser applications, such as cutting and welding.
What is the main purpose of a laser?
The main purpose of a laser is to focus electromagnetic radiation (light) on to a single point.
What are the conditions necessary to produce laser light?
To produce laser light, three conditions are necessary: a gain medium to amplify the light, an energy source to excite the atoms in the gain medium, and an optical resonator to select and amplify the light through stimulated emission. These conditions allow for the emission of a coherent and collimated beam of light with a narrow wavelength range.
What type of laser lighting is recommended for light shows?
RGB lasers are recommended for light shows as they can produce a wide range of colors by combining red, green, and blue light. These lasers are versatile and can create dynamic and vibrant visual effects for a captivating light show.
How do you produce two coherent sources of light?
To produce two coherent sources of light, you can use a laser to create a beam of light with a single frequency and direction. By splitting the laser beam into two using a beamsplitter, you can then generate two coherent sources of light that have the same frequency and phase relationship.
What makes laser light coherent?
Laser light is coherent because it consists of waves that are in phase with each other, meaning they have a constant phase relationship. This coherence is maintained by the stimulated emission process in the laser cavity, where photons are emitted in a synchronized manner. The coherence of laser light results in its ability to produce a narrow beam with consistent wavelength and phase.
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.
Why mirrors used in ruby and He-Ne laser?
Mirrors are used in ruby and He-Ne lasers to create an optical resonator cavity for the laser to oscillate and produce coherent light. The mirrors reflect the emitted light back and forth within the cavity, amplifying the light through stimulated emission process. This process helps to establish the necessary conditions for laser action, where the light waves are aligned and reinforced to produce a powerful coherent beam.
