When I was a kid, I remember a Pacific Telephone Magazine (dad was employed thereby) article about the invention of the Laser. Then I remember James Bond nearly being vivisected by a huge RED laser... Now I cut intricate and beautiful wood, acrylic, metal art with one... and for a buck, I can drive my cat crazy with one. My GOD that is progress! I am astounded this all happened in my 70 years.
some good "history of the laser" in the description. Lasers have been made in all wavelengths. Today, there's quasi-crystal lasers, lasers output shape have been controlled; it usually comes out looking like a globular cluster.
@PussyIsHere I just read he is Iranian / Persian. No mention of his religion but you may be right. Anyways, Ali Javan and Charles Townes are the GOATS of laser technology.
@@jamilshekinski He was clearly of Iranian descent, born in Iran (a multicultural country) to ZOROASTRIAN parents, Iran is also the country that is most advanced in that region in science and technology for a region. No offense, all the smart "Middle Eastern" people I've met have predominantly been Iranian. Iran has invented so many things, past and present including launching a satellite into space. Your little dump of a country has 0 history so you are literally stealing Iranian history which is amusing. He has nothing to do with Azerbaijan.
Gordon Gould invented the laser. This video is wrong! But the inventor did not build the first laser. People confuse the first built laser with the inventor. A lawsuit was filed by Gould who eventually won out as the actual inventor. Now, these to guys got the Nobel Prize. Even though Gould won the lawsuit, he did not get any prizes.
He is Iranian Azerbaijani. Iranian. Iranian is not a race. It's a nationality. You're from the country of Azerbaijan. Which Ali Javan is not from. Like millions of Iranians, who are of Azeri descent, but are IRANIANS.
At 7:09 they show a laser cutting the warning symbol for laser exposure. Made me laugh. This video pairs very well with another AT&T archive video about masers ua-cam.com/video/2tdiKTSdE9Y/v-deo.html
The first semiconductor laser was invented by Robert N. Hall at GE in Schenectady NY in 1962. Love how companies twist reality to make it look like they invented something when they did not.
Yes, Robert Hall developed the first semiconductor laser, and Nick Holonyak the first visible wavelength semicoductor laser, but both required cooling to be reliable. A solution to the problem- the double heterostructure laser- was proposed by Herbert Kroemer in 1963, and first demonstrated by Zhores Alferov in 1968, but it wasn't ready for production until 1970, when Morton B. Panish and Izuo Hayashi at Bell Laboratories successfully produced them en masse on wafers.

Most inspiring.
The optical Laser in principle was invented by Gordon Gould. He also created the term LASER.
Where is Ali Javan? That Iranian genius invented the neon gas laser.

30 year old retrospective video on a then 30 year old technology.
Wrong! The HeNe was first operated in 1960's (a few months after the ruby laser), NOT 1961!
Proud of our Azerbaijani scientist.

The research paper announcing the laser was published in *1958* by the two Bell Labs scientists in the video. So there's no twisted history here.
