In ultrafast laser systems, the actual pulse width of the laser is often affected by group delay dispersion (GDD), causing the pulse to be longer than expected, which in turn limits the system's peak power and time resolution. To achieve shorter pulse durations and higher peak intensity, high-performance dispersion compensation optical components, such as group delay interferometric (GTI) mirrors, chirped mirrors, and chirped mirror pairs, must be introduced into the laser system. These dispersion mirrors precisely control the phase delay of light waves, effectively compensating for the dispersion introduced by the laser and other optical elements, restoring the original pulse shape and enhancing the overall system performance.

Since dispersion mirrors play a key role in ultrafast lasers, they must have an extremely high laser damage threshold (LIDT) to withstand intense light power, while also requiring excellent spectral properties and tightly controlled group delay dispersion parameters. The design and manufacturing process of these dispersion mirrors need to ensure high density, precise control of coatings, and stability of the thin films to guarantee long-term reliability and performance stability.

WAVEQUANTA focuses on the ultrafast optics field, dedicated to the research, development, and production of high-quality GTI mirrors, chirped mirrors, and chirped mirror pairs. Our products not only perform excellently in spectral response, covering a wide working wavelength range, but also possess laser damage thresholds that are at the forefront of the industry, ensuring stable operation even under high power and ultrashort pulse conditions. By precisely controlling group delay dispersion (GDD), our dispersion mirrors help customers achieve sub-hundred femtosecond or even sub-ten femtosecond pulse compression and control, meeting the demanding requirements of ultrafast laser technology from fundamental scientific research to industrial applications.

Choosing WAVEQUANTA’s dispersion compensation solutions means you will benefit from advanced optical design and top-tier manufacturing process support, ensuring that your ultrafast laser system meets the highest standards in performance, stability, and durability, helping you continue to innovate and make breakthroughs in the field of ultrafast optics.

Note: To ensure optimal performance, it is recommended to store and use the mirrors in an environment with a temperature of 25°C and relative humidity of 40%-60%. If the mirror surface becomes contaminated, gently clean it with 99% pure alcohol and lint-free lens cleaning paper. Avoid using rough cloths, water, or cleaning agents with abrasive particles, as they may damage the coating.
