How to Create a Laser (and a Maser)
The laser is an iconic technology, forever linked to the idea of scientific progress. So why was it nearly called a loser? In this physics lesson, Es Einsteinium gives an in-depth discussion on lasers, starting from the beginning, where you’ll learn about masers (the laser’s predecessor). Learn about the functions and purposes (or lack thereof) of masers and lasers such as space communication and fiber optics in this lesson!
