How do lasers use infrared radiation
WebFeb 4, 2024 · The letters in the word laser stand for L ight A mplification by S timulated E mission of R adiation. A laser is an unusual light source. It is quite different from a light bulb or a flash light. Lasers produce a very narrow beam of light. This type of light is useful for lots of technologies and instruments—even some that you might use at home! WebThe laser wavelength can be tuned by altering the isotopic ratio of the carbon and oxygen atoms comprising the CO 2 molecules in the discharge tube. Construction [ edit] Because CO 2 lasers operate in the infrared, special materials are necessary for their construction.
