Damage-Resistant 1030nm Femtosecond Mirror, specifically designed for femtosecond and picosecond lasers and their systems, effectively addresses the three core concerns that matter most to you: Are standard mirrors suitable for femtosecond laser systems? Can they maintain the original temporal characteristics of the laser beam? Can they withstand high peak intensities? With our ultrafast mirrors, you no longer need to worry about these issues.

This series of mirrors covers the typical wavelengths of Yb:KGW, Yb:KYW, Yb:YAG, and ytterbium-doped fiber lasers. Using advanced Ion Beam Sputtering (IBS) dielectric coating technology, they offer the following significant advantages:

· High Reflectivity and Low Group Delay Dispersion (GDD)
Achieving a reflectivity of >99.8% at the design wavelength, while controlling the group delay dispersion (GDD) to extremely low levels (typical value <10 fs²), ensuring that sub-100 femtosecond pulses experience almost zero temporal broadening before and after the mirror, preserving the temporal structure and phase information of the ultrashort pulses.
· Outstanding High-Energy Endurance
Combined with a high-purity UV fused silica substrate and IBS coating design, the single-pulse laser damage threshold (LIDT) reaches >3 J/cm² (10 ns), enabling long-term stable operation in high peak intensity environments without worrying about coating fatigue or ablation.
· Excellent Environmental Adaptability and Long-Term Stability
IBS coatings, due to their high density and excellent adhesion, can effectively resist spectral shifts caused by changes in temperature, humidity, and vacuum conditions, ensuring long-term stability of the reflective properties even in complex environments.
· Wide Range of Applications
Suitable for ultrafast spectroscopy and time-resolved experiments, high repetition rate laser processing, chirped pulse amplification (CPA) systems, and three-photon microscopy, as well as industrial ultrafast laser processing and precision marking. It provides core optical protection for various ultrafast laser systems.

With exceptional optical performance and reliable environmental adaptability, this ultrafast laser line mirror is the perfect choice for high-precision, ultrashort pulse, and high-power laser applications, enabling you to easily achieve peak performance in both scientific research and industrial practice.

Precautions: To ensure optimal performance, it is recommended to store and use the mirror in an environment at 25°C with a relative humidity of 40%–60%. If the mirror surface becomes contaminated, gently wipe it with 99% or higher alcohol and a lint-free lens cleaning tissue. Avoid using rough fabrics, water, or cleaning agents containing abrasive particles, as they may damage the coating.
