Why is the size of a laser or electron beam measured in milliradians?
Aristaea
The size of a laser or electron beam is measured in milliradians. This is because they are subject to divergence.

What does laser beam mean?
A laser is the device itself, the beam is.. well, the beam coming out of the laser.
How can you get laser?
How can yo u get laser beam?What is laser beam characteristics and principles?
How did they know the distance of the earth to the moon?
Originally, the distance was measured by a system called parallax measurement. Today, it is measured by laser beam, and is accurate to within inches.
What is caution laser beam?
"Caution Laser Beam" is a phrase used on warning signs and labels to alert users and passersby that a laser beam may be present.
In a laser printer the beam detect mirror detects the laser beam by reflecting it to a blank?
optical fiber
What are the differences between a free-electron laser and a conventional laser?
Free-electron lasers were invented at Stanford University by John Madey. While these lasers share the same optical properties as conventional lasers, the main difference between the two is the principal they use to form the beam.
What is a laser modulator used for?
A laser modulator is used to change modulate a beam of light (or laser). The easiest way that they modulate the laser, or light beam, is by changing the rate at which the laser is emitted from the source.
How is magnesium welded with out it being ignited?
Some methods are used: - electron beam welding - laser beam welding - gas wolfram arc welding - gas metal arc welding - resistence welding - brazing
Laser beam needs electricity or not?
All lasers require electricity to operate. The laser beam that results from operation of a laser is electromagnetic radidation, not electricity.
What is the shape of the path of a laser beam?
Since a laser beam is light all moving on the same direction, the path of a laser beam will be a straight line, inless it is redirected by a reflective surface.
You wonder if high voltage and current can be deflected or reflected and similar to a laser beam from a Free Electron Laser machine?
A laser beam is a form of electromagnetic radiation, in the visible spectrum. At a lower frequency there are microwaves, which can be directed in narrow beams, and can be intercepted by an antenna and then converted back to an electric current. I don't recognise your idea of controlling beams of high voltage however.
Electron microscopes use a beam of light to produce a magnified image.?
It uses electron beam
