Is looking at a laser more dangerous than looking at a light-bulb of the same intensity?
Mastermask4
Yes. There is a huge difference between a 1-watt laser and a 1-watt light bulb. A 1-watt laser will burn a hole in your eye.

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 spiking in ruby laser?
The emission of laser beam through the semitransparent end face actually consists of spikes of high intensity emissions. This phenomen is called spiking of the laser.
Why laser produces Gaussian beam?
A laser produces a Gaussian beam because of the diffraction effect of the laser beam passing through an aperture. The electric field distribution of the beam follows a Gaussian shape due to the wave nature of light. This results in a beam that has a bell-shaped intensity profile with a narrower central peak and gradually decreasing intensity towards the edges.
What is special about laser light that makes it so useful compared to ordinary light from a light bulb?
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 voltage of laser is needed to injure a person?
It Isn't about voltage, it is about wattage. The amount ow watts the laser is. 10mw can blind someone and 10w can burn through skin. Anything over this is very dangerous and should on be used by professionals

Is the LaserComb hair implant procedure dangerous?
The LaserComb hair implant procedure is not dangerous if done correctly. There are 'rules' to follow to ensure safety such as not looking into the laser and not trying to repair the laser yourself.
Is it dangerous to look at a 30mw green laser pointer dot without goggles?
Yes! You could really go blind from looking to long at a green laser.
What is power broadening in lasers?
Power broadening is an effect whereby the line-width of a laser is broadened by the laser intensity itself. Higher laser intensity leads to a larger line-width. This can be explained by considering the decay rate of atoms from the upper to lower laser level. As the laser intensity increases, this decay rate (which is linearly related to the line-width) increases due to stimulated emission.
Is it dangerous to use a boombox if the cd lid is broken(Will the laser blind me)?
The laser won't blind you, as the CD will cover it when in use. However, the laser can be dangerous for your eyes so be careful.

Is it dangerous for a person to use a laser pen indoors?
Some laser pens are not dangerous indoors. A laser pen with five mW will not harm someone and is visible enough to see. But other pens which have one hundred mW are very dangerous and are a hazard.
How does laser light carry sound?
Basically, the same way AM radio waves do: by modulating the amplitude (intensity) of the carrier wave (the laser beam).
What does an argon laser do?
when argon is added to a laser the laser becomes 100 times more powerful. argon is a Nobel gas and is very heavy. and dangerous C:
How dangerous is it for kids to play with laser guns?
It is not at all dangerous. If the children are in a game and wearing vests then it is safe.
