Laser systems refer to technologies that utilize laser light for a wide range of applications, including cutting, welding, engraving, medical procedures, and scientific research. Laser systems involve the use of concentrated beams of light that are highly coherent and focused, allowing for precise control and manipulation of materials at a very small scale. They are used in various industries and research fields due to their high efficiency, versatility, and ability to perform tasks that are difficult or impossible with conventional methods. Advances in laser technology continue to expand the capabilities and potential applications of laser systems in areas such as communications, materials processing, and defense.
