Neodymium-doped glass is a type of glass that contains small amounts of the rare earth element neodymium. This doping process enhances the glass's ability to absorb and emit light, making it useful in various applications, including lasers and optical devices. The unique properties of neodymium allow the glass to produce specific wavelengths of light, particularly in the infrared range. The glass is often used in laser technology and optical filters, where precise control of light is essential. Neodymium-doped glass can also be found in some types of jewelry and decorative items, where its vibrant colors and light-transmitting qualities are appreciated.
