Semiconductor or diode lasers are the most used nowadays. The operation and materials used in this type of laser are shown in this post.
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.
For 40 years, nobody could explain how auroras in Jupiter were formed. Now, data from probes can give an answer.
For the first time, atoms were observed with a new type of microscope, which uses a photoinduced force to observe atomic nanometric structures.
This is the first of a series of posts related to lasers. This post’s topic is about the principle of laser operation.
A new formula for white paint got a reflectivity record, allowing to save energy with air conditioner and improve thermal isolation.
Three different atomic clocks made an ultraprecise comparison measure, within a quadrillionth of 1%, an advance in the new definition of a second.
Today’s subject is Raman spectroscopy. A very used technique in physics, chemistry, and biology to analyze materials’ molecular structure.
The 3D printer is revolutionizing object manufacturing. It’s an additive manufacturing technology, whose operation is today’s subject.
The Jiuzhang is a recently built quantum computer, which makes impossible calculations for a digital computer using photons, light particles.
