How many wavelengths does a laser beam have?
Answer Typically a laser (light amplification by stimulated emission of radiation) produces light of one frequency or of an extremely narrow band of frequencies. They initial laser "beam" was thought of as being one color, or having one frequency (monochromatic). But there are lasers that produce light across a broader spectrum, or on a multiple of (specific) frequencies, depending on the laser. A link is provided below to the Wikipedia post on the laser. Answer A laser produces an infinite number of wavelengths, but they are all very close to a characteristic single value. Answer If 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.
