Laser equipment are available for sale in Honolulu. Laser is short for Ligh Amplification by Stimulated Emission of Radiation (though it is no longer really used as an acronym). It is used for various applications, such as surgery (laser healing, surgical treatment, kidney stone treatment, eye treatment, dentistry- using a laser for cauterization cuts down on the blood loss), cutting, welding and heat treatment in industry, military applications, in research and development, and for lighting displays. Laser equipment can be of various types, depending on power, voltage, emission spectrum, and usage. One or more types are available in Honolulu. While using laser equipment, it is important to keep safety considerations in mind.
