AnswerA laser produces an infinite number of wavelengths, but they are all very close to a characteristic single value. AnswerIf the laser is pulsed then the shorter the pulse the larger the bandwidth (the range of frequencies) of the pulse. Femtosecond (one thousandth of a billionth of a second) pulses produce "white" laser light which contains all the visible frequencies.

Whats the highest class of lasers?
The highest class is Class 4.
What has wavelengths between 380 and 750 nanometers?
Visible light
If a painted wall reflects light with wavelengths 600 to 700 nm but absorbs light with wavelengths 400 to 500 nm what color is it?
It will be a dark red solution- like liquid bromine
What causes the dark bands observed in a solar spectrum?
The dark bands are caused from the differnet chemical elements which absorb light at specific wavelengths.
How long have lasers been around for?
Since 1960's
Where can one purchase lasers of different wavelengths?
Lasers of different wavelengths can be purchased from many sites online, such as Lexel Laser, and Wicked Lasers. Be sure to check the legality of the lasers in your country or risk losing them at customs.
Lasers emit what kind of energy?
Monochromatic, coherent, electromagnetic energy tuned over a wide range of frequencies/wavelengths.
Why pressure of Ne is kept small in He Ne lasers?
It was found that the pressure of Ne is kept small in He-Ne lasers for having the highest gain in the visible spectrum. But other visible also has infrared lasing wavelengths by using mirror coating.
What type of laser is used in laser hair removal?
There isn't technically a "type of laser," but more of a wavelength used since lasers are really just single wavelengths. Wavelengths used now are 755 for lighter skin to as high as 1064 for darker skin.
What damage can lasers do?
lasers damage call composition
Can the sun shoot lasers?
no because it has no lasers inside of it
How lasers work in road scanners?
How do lasers work
When was With Lasers created?
With Lasers was created on 2007-06-05.
When was Springfield Lasers created?
Springfield Lasers was created in 1996.
Can laser be used in plural as in lasers?
the plural of laser is lasers. for example I have many lasers. you don't say I have many laser.
Are rubies used in electronics?
Yes, rubies are used in some LASERs. These LASERs are (not surprisingly) called ruby LASERs.
What type of lasers does Erchonia manufacture?
Since the early 1970s Erchonia lasers have been classified by wavelength and maximum output powers into four classes. The lasers are used in treatment of neck and shoulder pain, breast augmentation, acne, laser assisted body augmentation. The types of lasers they use for these treatments include 3LT Lasers, Custom Design Lasers and Zerona Lasers.
