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.
What else can I help you with?
Whats the highest class of lasers?
The highest class is Class 4.
How long have lasers been around for?
Since 1960's
Lasers are not a part of any of these processes except for______?
Inertial confinement fusion Apex
What naturally occurring substance will cut diamonds?
The only substance capable of cutting diamond would be it's self. Now, Lasers can also cut diamonds. But I don't consider lasers a substance.
How long does a laser take to warm up?
There's more than one type of laser. Diode lasers are pretty much ready to go immediately, but you don't want them to push too much power, as they can then heat up to the point of failure. Other lasers, particularly high powered chemical lasers, rely on a several complicated sub-systems to fire, and will need quite some time to get ready for action.
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.
What are the example of liquid laser?
Some examples of liquid lasers are dye lasers, which use organic dyes dissolved in a solvent as the gain medium, and liquid crystal lasers, which use liquid crystal materials to create the gain necessary for laser emission. These liquid lasers have tunable emission wavelengths and can be used in various research and industrial applications.
What is the difference between lasers and tunable lasers?
All tunable LASERs are LASERS, however not all LASERS are tunable. In a tunable laser the lasing medium, which is typically a gas, dye or crystal, can be altered to produce slightly different frequencies, thus allowing the laser to be 'tuned' or frequency changed where most LASERS produce a very narrow band of radiation frequencies.
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 do lasers emit?
Lasers emit highly concentrated beams of coherent light, typically within a narrow range of wavelengths. This focused light can have various applications in areas such as construction, medicine, communication, and entertainment.
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.
Is mercury lamp a monochromatic source?
Mercury lamps are not strictly monochromatic sources. They emit light at multiple wavelengths across the visible spectrum and also in ultraviolet ranges. While they may emit some predominant wavelengths, they are not considered fully monochromatic like lasers.
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.
What are the differences between a free-electron laser and a conventional laser?
Free-electron lasers were invented at Stanford University by John Madey. While these lasers share the same optical properties as conventional lasers, the main difference between the two is the principal they use to form the beam.
Can lazers effect the body?
Yes, lasers can affect the body in various ways depending on their type, intensity, and exposure duration. Low-level lasers are often used in medical therapies for pain relief and tissue healing, while high-intensity lasers can cause burns or damage to tissues and organs. Prolonged exposure to certain wavelengths of laser light can also lead to eye injuries. Proper safety measures are essential when using lasers to minimize potential harm.
Why is krypton used in flash photography and lasers?
Krypton is used in flash photography and lasers primarily due to its ability to produce intense, bright light when electrically stimulated. In flash photography, krypton gas generates a quick, powerful burst of light, providing excellent illumination for capturing fast-moving subjects. Additionally, in lasers, krypton can be used in gas lasers to emit coherent light at specific wavelengths, making it useful in various applications, including medical and scientific fields. Its stability and efficiency in these contexts make it a valuable choice.
