Term: neodymium laser https://doi.org/10.1351/goldbook.N04103 Definition: A CW pulsed laser emitting radiation from excited Nd3+ principally occurring around 1.06 µm (the precise position depends on the matrix). The Nd3+ is present as a dopant in suitable crystals (e.g. yttrium–aluminium garnet, YAG) or in suitable glasses (phosphate, silicate, etc.).
