Laser types (Part 3, fiber laser)
In this third part, are shown the operation principle, advantages and disadvantages, and the applications of fiber laser.
The BASE experiment with protons and antiprotons
The new BASE measure with high precision didn’t show substantial differences between protons and antiprotons, beyond the electric charge signal.
Laser types (Part 2, diode lasers)
Semiconductor or diode lasers are the most used nowadays. The operation and materials used in this type of laser are shown in this post.
