A laser is a beam of very strong and focused light. It is possible for this light to damage the retina of your eye permanently, and you will lose all or part of your vision.
the laser was invented.....
construction and working of semiconductor laser
An infrared beam is often used on a security alarm. When the beam is broken, an alarm sounds. The beam is invisible because infrared is electromagnetic radiation that has longer wavelengths than the ones with visible light.
If the laser is in Hollywood it is possible, anywhere else in the world? no, impossible

How can yo u get laser beam?What is laser beam characteristics and principles?
Creating a laser beam at home is not recommended due to safety concerns and the complexity of the process. Lasers can be dangerous if not handled properly and can cause harm to eyes and skin. It is best to purchase a laser pointer or device from a reputable source for any laser-related experiments or projects.
Laser Safety procedures are often specific to a particular laser installation. In general, however, the following apply:don't look directly at the laser beamknow where the laser beam path isenclose the beam path as much as possibleensure that warning signs and labels are properly placednever point a laser beam at a personuse appropriate protective eye wear if exposure to a Class 3B or class 4 beam is possiblewear protective clothing is exposure to a Class 4 beam is possiblenever stare into a Class 2 laser beamensure that laser users receive adequate laser safety training
A laser beam is a narrow, focused, and intense beam of light produced by a device called a laser. Laser beams are used in various applications such as cutting, welding, medical procedures, and communication systems due to their ability to deliver high energy in a precise manner.
A caution laser beam is a warning sign used to indicate the presence of a laser that may be harmful to the eyes or skin. It alerts individuals to use proper protection and avoid direct exposure to the laser beam.
One can see an invisible laser beam by using special equipment like a laser beam detector or by observing the beam's reflection off of particles in the air.
Yes, a mirror can effectively reflect a laser beam.
To see a laser beam, you can use special materials like smoke or fog to make the beam visible. The light from the laser reflects off these particles, allowing you to see the beam.
The intensity of a laser beam refers to the amount of power per unit area that the beam carries. It is a measure of how concentrated the energy is in the beam.
The power of a laser beam is typically measured in watts (W). This measurement indicates how much energy the laser beam is emitting per unit of time.

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.
