RE: 50 years of Laser

It has been a decade since I took a physics class, but I'm pretty certain that atoms don't transition between levels- electrons in the atom do. The schematic in the comic is right, but the statements are wrong.

murthymail, the comics which you have heard about the first one. And I just want to say you that the laser has been used in a variety of ways since its invention 50 years ago. It has been used in medicine for surgery and dentistry, with a rising popularity in laser eye treatments.

It is very good comic and easy to understand about 50 years of Laser. I like to salute all scientists who contribute their life to give a very good gift to counties. And because of their contributes laser light is in our life, and now it over 50 years.
