Recently, a group of South Korean scientists have developed a laser device that will create less pain while inserting an injection into his/her body. Scientists from Seoul National University in South Korea have developed a laser called “Erbium-doped Yttrium Aluminium Garnet”, in short Er:YAG.
Curiosity has been making headlines ever since it successfully landed on Mars. The world has been waiting eagerly to get further updates about the rover. And now, NASA has revealed that the rover has shot its first laser on a Martian rock to analyze its components.
Lasers have come about to play a very significant role in the realm of technology. In view of this, Defense Advanced Research Projects Agency (DARPA) has launched a campaign to ramp up the development in this field. The agency is asking researchers to propose methods for creating high-speed lasers.
To fight against cancer, researchers are continuously working to find out newer ways. They are upgrading the current methods to treat cancer. Recently, researchers at the University of Tennessee’s Space Institute have developed a Femtosecond laser. Scientists are hoping to use it as a weapon against cancer.
Around three months earlier, we reported that scientists at Ohio State University been planning to test a 500 trillion watt laser. Now, another group of physicists at the Lawrence Livermore National Laboratory’s National Ignition Facility in Livermore, California have broken the record. The new laser can deliver the highest-power laser shot with a collection of beams delivering more than 500 trillion watts of peak power. At present, this is the most powerful laser in the world.
Destruction of planets is nothing new in Sci-Fi movies. We have seen how planets get destroyed in many Sci-Fi movies. But practical world is different from cinematic world. A study suggests that our best chance of defending the planet from asteroids is to equip spacecrafts with solar-powered lasers. And, the technology required to do this already exists.
In the movies or cartoons, we have seen people are fighting with laser weapons. We have seen this used in the Star Wars universe. This laser swords were popularized as Lightsaber in Star Wars. Till now, a Lightsaber was a fictional weapon. But Wicked Lasers has developed a real laser sword. Finally, fiction comes to reality!
When we hear the word Laser, first thing comes to our mind is, colorful lights emerged from different tiny points. By mixing the colors in different ratios, we get new types of color. Till now, one laser can radiate a specific color. Recently, a researcher team has made a single material that can produce several different wavelengths and therefore different colors of laser light emerge.
