Is laser light likely to be more or less energetic than sunlight?

If you mean the intensity, lasers win by a huge margin. The average solar flux at the top of the atmosphere is 0.1367 W/cm2. Commonly available industrial lasers can hit 5000 W/cm2. The attached link describes reaching a flux of 0.7 x 10^22 W/cm2.

What is the three dimensional image produced by laser light?
the three-dimensional image produced by laser light is a hologram
Why the laser go in straight line and in same size?
A Laser (Light Amplification by Stimulated Emission of Radiation) is "coherent" light. That means that all of the light is traveling in the same direction. Unlike a lightbulb, flashlight, or other "normal" light source where the light is going in all directions out from the center of the source, a Laser's light is all going in a straight line away from the source. This is why you cannot see a laser until it hits something (dust particles in the air, for example), and also why looking directly into a Laser (yes, even one of the cheap pointer types) can cause permanent damage to your eye.
What is the geometric term of a beam from a laser?
It is a ray [of coherent light], a physical term.
What is a real life example of a ray?
the light from a flashlight. you know the origin of light but you cannot measure exactly the distance the light travels or the sun's ray of light...same same Or Just an laser beam
Can plants survive without light?
Some plants like mushrooms and fungi can survive without sunlight.
Is a laser artificial sunlight?
No. Laser light is artificial light, but it is not sunlight.
Can sunlight be used for a laser?
No. A laser is a bean of light that propagates in one direction with little spread and generate light only over a very small range of wavelengths. The rays of sunlight are parallel only because of our great distance from the sun. Sunlight can be focused to a point using mirrors or lenses, but will spread out beyond that point, rather than as a coherent beam light a laser. Additionally, sunlight consists of the entire spectrum of light.
How does different light affects things?
Visible light consists of a number of wavelengths. Blue light is the most energetic, red light the least energetic. Green plants grow best in red or blue light (sunlight is a mixture of wavelengths) and do not grow in green or yellow light. Light intensity will affect the growth of plants. Laser light (high intensity with very narrow wavelength) can be used to cut and obviously hurt if used incorrectly. Some people are photo sensitive and light can cause them pain. Green plants are photo sensitive and will grow towards the light.
What produces light?
Certain substances produce light when they are illuminated by more energetic radiation, a process known as Fluorescence. Some substances emit light slowly after excitation by more energetic radiation. This is known as Phosphorescence
What is a laser light with holograph?
a laser light with a holograph is a laser light with holograph.
Can light cause a fire?
Yes it can. Sunlight when directed to an area with a magnifying glass can create fire. also Laser is also light and can be used to burn or create fire.
A good example of white light?
White light is another name for polychromatic light. That is light that contains more than one wavelength. For example, sunlight is white light. An example of monochromatic light is a sodium vapour lamp or a LASER.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
What dose laser stand for?
Light amplification by stimulated emission of radiation(LASER or laser)
What light is only one color?
Monochromic light can be photons in a narrow energy range emitted by a laser. Sunlight looks uniform but it is actually composed of all of the wavelengths of visible light (except for a few that have been absorbed in the atmosphere).
Difference between laser and torch light?
laser light rays don't spread and torch light ray's do
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!
