text: Also Green lasers are a type of solid-state laser that emit light in the green portion of the visible spectrum. The green color is produced by using a crystal, such as neodymium-doped yttrium aluminum garnet (Nd:YAG), as the lasing medium.Green lasers are popular in military and industrial applications because they can be seen more easily in daylight than other colors, such as red. They can also be used for rangefinding, target designation, and laser light shows. Additionally, green lasers have a higher efficiency than red lasers, allowing them to produce more light with less power.
