You've probably seen lasers used as pointers at a talk, or you may even have your own lazer pointer at home that you play around with because, put simply, lasers are cool. But did you know that lasers are actually really useful for science too? With lasers they can levitate stuff. A lazer beam has an intensity profile where typically the intensity is higher in the center, which means there are more photons coming out at the center of a lazer beam. Biologists use them as optical tweezers. Some scientists use lasers for cooling stuff, while more comonolly others use them for heating up stuff. With an x-ray laser, you can image biological reactions and make little science movies. X-rays have a very short wavelength which means they can image very small stuff, including individual atoms. The lazer is pulsed which means it can take snapshot images of these reactions very quickly before the sample is destroyed.
