Laser glass is a solid-state laser working material based on a glass matrix, widely used in various types of lasers. It serves as the core material for achieving optical amplification and laser output. Its fundamental structure consists of two parts:

• Matrix Glass: Provides the foundation for physical and chemical properties, requiring high transparency, optical homogeneity, and thermal stability. Common types include silicate, phosphate, and other glass systems.
• Activating Ions: Determine spectral characteristics, with rare-earth ions (such as Nd3?, Yb3?, Er3?, etc.) being the mainstream. Among these, neodymium-doped glass has become the most widely used laser glass due to its strong room-temperature laser output capability and high quantum efficiency.

Significant Characteristics of Laser Glass

Material Advantages

• Preparation Flexibility: The matrix glass has a wide formation range, allowing customization of laser performance by adjusting the types and concentrations of activating ions. It can be easily processed into various shapes such as rods, plates, and fibers, with sizes ranging from micron-level optical fibers to meter-level large rods.
• Excellent Optical Performance: Features high transparency (reduced light scattering due to short-range order and long-range disorder structure), isotropy, and good optical homogeneity, making it suitable for high-power laser transmission.
• Cost-Effectiveness: Raw material purity requirements are lower than those for crystalline materials, and the preparation process is relatively simple with short manufacturing cycles, making it suitable for large-scale production.
