Quarks charm on protons
A new study suggests that exist subatomic particles called quarks charm inside the protons.
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.
The Jiuzhang 2.0 was built
Was anounced the Jiuzhang 2.0, an improvement of photonic quantum computer built last year, and billions of times faster than the predecessor.
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.
Laser types (Part 1, gas lasers)
This is the first post of laser types series. Toady’s subject is the operation of the main gas lasers, which were created in the 1960s.
Photoinduced force microscope
For the first time, atoms were observed with a new type of microscope, which uses a photoinduced force to observe atomic nanometric structures.
How does the laser work?
This is the first of a series of posts related to lasers. This post’s topic is about the principle of laser operation.
What is Raman spectroscopy?
