The medium can be a gas, crystal, semiconductor, liquid, or optical fiber.<\/p>\n\n\n\n<p class=\"gutenx-wrapper wp-block-paragraph\">When energy enters the system, atoms absorb that energy and become excited. As the atoms return to lower energy states, they release photons.<\/p>\n\n\n\n<p class=\"gutenx-wrapper wp-block-paragraph\">Those photons trigger nearby excited atoms to release identical photons in a process called <strong>stimulated emission<\/strong>. Mirrors inside the laser bounce the light back and forth, amplifying it until a powerful beam exits through one side.<\/p>\n\n\n\n<p class=\"gutenx-wrapper wp-block-paragraph\"><strong>The process typically follows these steps:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list gutenx-wrapper\">\n<li class=\" gutenx-wrapper\">Energy excites atoms<\/li>\n\n\n\n<li class=\" gutenx-wrapper\">Excited atoms release photons<\/li>\n\n\n\n<li class=\" gutenx-wrapper\">Photons stimulate identical photon release<\/li>\n\n\n\n<li class=\" gutenx-wrapper\">Light amplifies between mirrors<\/li>\n\n\n\n<li class=\" gutenx-wrapper\">A concentrated beam exits the laser<\/li>\n<\/ol>\n\n\n\n<p class=\"gutenx-wrapper wp-block-paragraph\">The result is one of the most controlled forms of light ever created.<\/p>\n\n\n\n<div style=\"height:51px\" aria-hidden=\"true\" class=\"wp-block-spacer gutenx-wrapper\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading gutenx-wrapper\">Who Discovered Lasers Initially?<\/h3>\n\n\n\n<p class=\"gutenx-wrapper wp-block-paragraph\">The scientific foundations for lasers began with <a href=\"https:\/\/www.aps.org\/archives\/publications\/apsnews\/200508\/history.cfm\" target=\"_blank\" rel=\"noreferrer noopener\">Albert Einstein in 1917<\/a>.
