NAP Nd:Glass

NAP Neodymium-doped phosphate glass is created specially for high average power applications. NAP2 and NAP4 are two types of new laser glass with high thermal shock resistance properties, which have higher thermal conductivity, lower coefficient of thermal expansion and modest emission cross section. They are served for laser systems with high repetition rates and high energy rates and high energy, which have broad applications in laser ranger, laser peening and pump laser for OPCPA systems.
