The "super" laser brings together the power of multiple laser beams directed into a single

intense output using an ultra-pure diamond crystal at the point of convergence. Credit: Macquarie University Though it's not big enough or strong enough to destroy a planet, scientists have developed an amplified laser reminiscent of the Death Star from "Star Wars," according to a new study. The futuristic superweapon combines multiple laser beams into one destructive blast, the researchers said. The idea of merging laser beams is not new, nor has it been limited to science fiction before now. A decades-old Russian missile defense project looked to use liquid as a beam combiner, but that project was abandoned after it was deemed not practical. A similar project in the U.S. investigated laser fusion, but using different materials. Now, a team of Australian scientists has combined the principles of these two research projects and applied them to a new material: diamond. An ultrapure diamond crystal is the key to a new proof-of-concept amplified laser. By placing a diamond at the point of convergence of the different laser beams, the power of each individual beam is transferred into one potent laser beam, the researchers said. This power transfer occurs due to Raman scattering — when particles are dispersed and excited to higher energy levels — which is especially strong in diamond, according to the scientists.
