Daumen Orbital Space Lasers Now like i said this laser is not very powerful but i have one with me here today that is pretty powerful and you shouldn't play with it at home. so i don't want to shine it on my hand so to show it to you i'm going to use a little bit of water. This spark of science is presented by ben szutor from the centre for doctoral training for applied photonics. listen to find out more about light, lasers and light engineering. Though laser physics was born from quantum ideas, the laser itself became a tool for probing even deeper into quantum mechanics. today, researchers use lasers to explore quantum entanglement, teleportation, and even the very nature of time and space. A laser uses a pair of mirrors facing each other—an optical resonator—to build up the light energy in the beam. as light bounces back and forth between the mirrors, it passes through the laser material, increasing in intensity with each pass as more excited atoms emit additional photons.

First predicted by einstein more than a century ago, lasers have shaped our modern technological landscape. but how do they work?. A laser is created when electrons in the atoms in optical materials like glass, crystal, or gas absorb the energy from an electrical current or a light. that extra energy “excites” the electrons enough to move from a lower energy orbit to a higher energy orbit around the atom’s nucleus. Lasers form rather more of a 'tool' and so demonstration experiments are relatively few. however some ideas and an explanation of the workings and other details of a laser are given. All light sources convert input energy into light. in the case of the laser, the input, or pump, energy can take many forms, the two most common being optical and electrical. for optical pumping, the energy source may be a lamp or, more commonly, another laser.
