The Advantages of SiC Mirrors and Bena Optics’ Processing Capabilities

In modern industrial and research fields, high-power laser technology is playing an increasingly important role, widely used in laser cutting, welding, additive manufacturing, and high-energy physics experiments. However, as laser power continues to increase, the limitations of traditional mirror materials (such as copper or glass) are becoming apparent, especially in terms of thermal stability, resistance to thermal deformation, and durability. At this point, silicon carbide (SiC) mirrors, with their excellent physical properties, have become the ideal choice for high-power laser applications.

The reason SiC mirrors are highly favored is primarily due to their excellent thermal performance. SiC material has an extremely high thermal conductivity (approximately 120-200 W/m·K), which can quickly dissipate the heat generated by the laser, avoiding thermal deformation. This is crucial for high-power laser systems because thermal deformation can lead to a decline in beam quality, affecting processing accuracy. Additionally, the specific stiffness (stiffness-to-density ratio) of SiC is 3-4 times that of traditional materials like copper or glass, meaning that SiC mirrors can be designed to be lighter while maintaining the same stiffness, thereby reducing system load and improving dynamic performance.

SiC has an extremely low thermal expansion coefficient (approximately 4.0×10⁻⁶/K), maintaining excellent dimensional stability even in high-temperature environments, ensuring the long-term reliable operation of laser systems. More importantly, SiC material can withstand direct exposure to high-power lasers without easily being damaged, making it particularly suitable for mirrors in high-energy lasers.
