Technology evolves at a rapid-fire pace. That’s why we’ve built an easy-to-use glossary to help you better understand the terms, technologies and trends that impact your business.


Term that was originally an acronym for “light amplification by stimulated emission of radiation”. A laser usually consists of a light-amplifying medium placed between two mirrors. Light not perfectly aligned with the mirrors escapes from the sides, but light perfectly aligned will be amplified. As one mirror is made partially transparent, the result is an amplified beam of light that emerges through the partially transparent mirror.
