Neodymium lasers are a type of solid-state laser that use neodymium ions as the active medium. These lasers typically emit light at a wavelength of 1064 nanometers, which falls in the infrared spectrum. They are known for their high power output and efficiency, making them suitable for various applications, including industrial cutting, medical procedures, and scientific research. The construction of a neodymium laser usually involves a crystal, such as neodymium-doped yttrium aluminum garnet (Nd:YAG), which is pumped by a light source, often a flashlamp or another laser. The emitted light can be further manipulated using optical components, allowing for precise control in applications like laser surgery and laser engraving.
