Nd:YAP (Neodymium doped Yttrium Aluminum Oxide, Nd3+:YAlO3) is a crystal material commonly used in solid-state laser applications. It is a transparent crystal that is highly efficient at absorbing and emitting light, making it well suited for use in laser systems. The efficiency of Nd:YAP is further enhanced by the presence of neodymium ions, which provide the active laser medium. This material is typically used in high-power laser systems, where it is able to produce high-intensity laser output with a high degree of efficiency. Additionally, Nd:YAP has a high thermal conductivity, which makes it ideal for use in high-power laser systems that require cooling to maintain stable operation.
