NAP Nd Glass (Neodymium Glass) Description
NAP Neodymium-doped Phosphate Glass is specially manufactured for high average power applications. NAP2 and NAP4 are two new types of laser glasses with high thermal shock resistance. They have higher thermal conductivity, lower thermal expansion coefficient, and moderate emission cross-section. They are used in laser systems with high repetition rate, high energy rate, and high energy, and have a wide range of applications in laser rangefinders, laser shot peening, and pump lasers of OPCPA systems.
