Nd,Ce:YAG (Neodymium and Cerium Doped Yttrium Aluminum Garnet) crystal is a high-performance laser material engineered for enhanced energy efficiency, superior thermal stability, and improved optical gain. With optimized neodymium and cerium doping concentrations, it enables stable lasing operation at 1064 nm, making it ideal for high-power laser systems, medical applications, industrial processing, and scientific research. Nd,Ce:YAG crystals offer strong resistance to thermal degradation and improved pumping efficiency, ensuring reliable and precise laser performance in demanding optical environments.
Product Overview:
Nd,Ce:YAG crystal is a modified version of the traditional Nd:YAG crystal, doped with cerium (Ce) ions to enhance its spectral utilization. The cerium ions effectively absorb photons from the ultraviolet (UV) spectrum and transfer the energy non-radiatively to the neodymium (Nd) ions, significantly improving the electro-optic conversion efficiency. Compared to conventional Nd:YAG crystals, the Nd,Ce:YAG crystal improves the electro-optic conversion efficiency by 30%-50%. This makes it an ideal material for low repetition rate and high pulse energy lasers, with applications in laser ranging, medical lasers, and more.
Key Features:
- High Efficiency:The addition of cerium ions improves the spectral utilization, increasing the electro-optic conversion efficiency.
- Low Threshold:The crystal has a lower laser threshold, allowing for high-efficiency output at lower power.
- UV Radiation Resistance:Excellent resistance to UV radiation, making it suitable for high-energy laser environments.
- Good Thermal Stability:The crystal maintains stable performance under high power and high heat conditions, making it ideal for high-intensity lasers.
- Excellent Repetition Rate Characteristics:It features excellent performance at low repetition rates, ideal for lasers with frequent pulsed output.
Applications:
- Laser Ranging:Widely used as an efficient and stable laser source for compact laser rangefinders.
- Medical Lasers:Extensively used in laser treatments and surgeries, particularly for precise laser output.
- Low Repetition Rate Lasers:Ideal for high-pulse energy, low repetition rate laser systems.
- High-Energy Lasers:Suitable for high-pulse energy laser systems, offering excellent electro-optic conversion and resistance to UV radiation.
