How bright is the laser in a laser printer?
Bright, like all laser. It is about as bright as a low power laser pointer. It is usually a class one laser and can not hurt you, but make sure you check it's class before opening the printer, though I would not suggest opening it in the first place.

How will you measure the thickness of human hair?
If you get a normal red laser pointer, you can pretty easily measure it at home. The wavelength of a red laser pointer is typically around 670 nanometers, the one you select may state differently; make note of it. Take one of your hairs and suspend it in front of the laser somehow, but make sure its exactly 1 meter from a flat surface. When you turn on the laser, you should see a dashed line pattern on the board. Measure the distance from the center bright spot to the farthest bright spot you can see and count how many this is. The thickness of your hair is (laser wavelength)*(distance to flat surface)/(distance to bright spot). Then multiply this number by the number of bright spots you counted. So, lets say i could count up to 4 bright spots before it got too dim; i measure the distance from the center to this one to be 5 cm; laser is 670nm and my flat surface is 1 meter away. My thickness is (670*10^-9)*(1)*4/ (.05) = 54*10^-6 meters = 54 micrometers
What are some of the best pointing devices when it comes to clear views on powerpoint presentations?

How does a bar code laser scanner work?
A bar code laser scanner works by shining a bright light (laser light) at the barcode and measuring the reflected beam. In order to scan the entire barcode very quickly, the light is bounced off a spinning disk to cover the entire barcode in one pass.
Why is a lasor beam have more enery then a light bulb?
Laser beams have a semi mirror inside of it that only allows it to go when the light is bright enough. Lightbulbs do not have that.
How often should you get your teeth whitened using a laser procedure?
Using a laser with a whitening gel, this is an in-office bleaching system. The length of time in the cosmetic dentist's chair depends on the degree of discoloration you have.One visit is usually all it takes for a bright smile.
How would one go about making tiny model lasers using LEDs?
LEDs are not LASERs and cannot LASE. If you want a small LASER, spend the money for a real LASER Diode. They are relatively cheap these days.There is a small chance that a large number of bright LEDs might be usable as a pump for a dye laser. Try researching that. Still I'm sure a COTS LASER Diode would be easier and cheaper.
What is the list of weapons that start with laser?
The list of weapons that start with laser are: Laser axe Laser bow Laser chaingun Laser chainsaw Laser cannon Laser crossbow Laser daggers Laser gatling gun Laser knife Laser machete Laser machine gun Laser rapier Laser rocket launcher Laser scythe Laser shotgun Laser slingshot Laser sword Laser tommy gun Laser whip and countless others
