Laser technology has been present for hundreds of years and forms a base for a lot of modern technology. Lasers are vital for minute manufacturing, surgery, communication and in some cases weaponry. Lasers come in many shapes from continuous wave, low power lasers to gigawatt pulse lasers, each designed with a specific purpose in mind.
What is a Laser?
A LASER, short for "light amplification by stimulated emission of radiation", is akin to a flashlight generating light, but the light is highly uniform and focused, leading to very small scattering and high energy content in the beam. Because of the uniformity lasers are capable of they can be finely tuned and reliable for measuring and targeted destruction. Surgery can be performed with lasers where wounds are immediately cauterised, minimizing bleeding and simultaneously making minimal damage on the body. Lasers are frequently used as incredibly precise measurement devices.
