What is a laser?
A laser is many very useful inventions use lasers. So do many inventions to entertain us. CD and DVD players use lasers. Bar code readers in stores use lasers. Doctors use lasers to do delicate surgery, such as eye surgery. Lasers carry TV and telephone signals over special cables. Metal workers use lasers to cut and weld metal into everything from street light poles to cars. Workers in clothing factories use lasers to cut through hundreds of layers of fabric at once.
What dose a laser do Most people know the word laser, but do they know what it really is? What's the difference between ordinary light and laser and what does laser really stand for? Let's start with the last question. Laser is an acronym, that is a word made up of initial letters. You could use the complete name: light amplification by stimulated emission of radiation but that's a bit awkward, let's keep to laser.
History of Lasers
This paragraph is about how the invention of the laser. In the early 1900's a guy named Albert Einstein started making the laser. About 40-60 years later, a guy named Theodore Maiman finished making the laser
Who invented the laser? According to Marry, Bells the invention of the laser, which stands for light amplification
By stimulated Arthur L. Schawlow can date emission of radiation, to 1958 with the publication of the scientific paper, Infrared and Optical Masers,, who was then a Bell Labs researcher, and Charles H. Townes, a consultant to Bell Labs.
How was the laser invented? Gordon Gould was the first person to use the word "laser". There is good reason to believe that Gordon Gould made the first light laser. Gordon Gould was inspired to build his optical laser starting in 1958. He failed to file for a patent his invention until 1959. As a result, Gordon Gould's patent was refused and his technology was exploited by others. It took until 1977 for Gordon Gould to finally win his patent war and receive his first patent for the laser.
I just told you some Information about the laser. I hoped you enjoyed it.
