Description
The Nd:Ce:YAG crystal, also known as Neodymium Cerium doped Yttrium Aluminum Garnet, is a highly efficient laser material renowned for its versatility and performance. This advanced crystal is engineered to deliver superior laser energy output, making it an ideal choice for a range of demanding applications. By incorporating Cerium as a sensitizer for Nd3+ ions, the Nd:Ce:YAG crystal exhibits strong absorption in the UV spectral region during flashlamp pumping. This unique composition ensures efficient energy transition to the Nd3+ excited state, resulting in reduced thermal distortion and enhanced laser energy output compared to traditional Nd:YAG crystals. One of the standout features of the Nd:Ce:YAG crystal is its ability to support high-power lasers with excellent beam quality. The lasing wavelength at 1064 nm, along with the laser damage threshold and thermal conductivity, is consistent with that of Nd:YAG, ensuring reliable and robust performance. This makes it an exceptional choice for applications requiring precise and powerful laser capabilities. In terms of manufacturing, the Nd:Ce:YAG crystal benefits from Crystech's comprehensive in-house production process, which includes crystal boules growth, cutting, polishing, and coating. This ensures high-quality standards, competitive pricing, and fast delivery, backed by excellent customer service. The crystal's physical and optical properties, such as its cubic crystal structure, high melting point, and significant emission cross-section, further enhance its appeal for various industrial and scientific applications.
