Laser is non diverging one and monochromatic. It is coherent and hence highly intense. So laser could be sent even to reach moon's surface and get it back reflected. So distance of astronomical objects could be found.

What is the difference between laser diffraction and ordinary light diffraction?

Laser diffraction involves the use of a laser beam to analyze particle size distribution, providing more accurate and precise results compared to ordinary light diffraction. On the other hand, ordinary light diffraction uses a broader spectrum of light, making it less specific and more prone to errors in measurement. Laser diffraction typically has a higher resolution and can detect smaller particle sizes than ordinary light diffraction.


Can you laser cut brass?

Yes, brass is a material that can be laser cut. However, it's important to use the appropriate laser settings and techniques to ensure a clean and precise cut due to brass reflecting more laser energy compared to other materials.


Do laser beams exist?

Yes, laser beams exist. They are intense beams of light with specific properties that make them useful in various applications such as cutting, welding, medical procedures, and communication technologies.


How many amps does a laser printer draw?

An ordinary one would take about 0.2 amp on 120 v, or 0.1 amp on 240 v.


How is laser light different from incandescent light?

The intensity of light from most light sources is inversely proportional to the square of the distance from the source. So the intensity two meters from an incandescent lamp is one quarter of the intensity at one meter, and at three meters from the lamp the intensity is one ninth of the intensity at one meter. Laser light ideally has the same intensity at any distance.

What is the cost of an ordinary Laser Computer?

There is no such thing as a laser computer. A laser printer costs about $400.


When is a laser diode module a useful thing to have?

A laser diode module is useful when a small laser with lower power usage is needed. The diode is used in a multitude of fields, including life science, industrial, and scientific instrumentation.


How does CO2 laser cutting work?

CO2 laser cutting work operates via producing infrared beams. For this reason, special materials are required, such as gold mirror or zinc, as these materials are high in thermal conductivity, which is useful in high power applications.


Who would find alexandrite to be useful?

People would find it useful because when its cut it gets melted and used for laser hair removal. It is called "Alexandrite laser hair removal".

What is the difference between a laser and an ordinary light in terms of colors?

A laser produces coherent light that is monochromatic, meaning it emits a single color or wavelength of light. In contrast, ordinary light consists of multiple wavelengths, producing a range of colors. This is why lasers are often used in applications that require precise and specific colors.


What's better long term: Laser or Ink-jet printers?

Laser printers are much more better than the ordinary ink jet printers for sure as they are faster and more durable than the ordinary ink jet printer ounces


What is special about the light in a laser beam?

The light in a laser beam is coherent, which means that all the light waves are aligned and have the same wavelength and phase. This allows laser light to be focused into a tight beam with high intensity and low divergence, making it useful for various applications such as cutting, surgery, and telecommunications.


How lasers and ordinary light different?

Lasers produce coherent and focused light of a single wavelength, while ordinary light sources emit incoherent light of various wavelengths. Lasers also have a much higher intensity and can be tightly focused over long distances compared to ordinary light sources. Additionally, lasers have a very narrow beam divergence, whereas ordinary light sources have a broader dispersion.
