In ultrafast laser systems, the actual pulse width is often affected by group delay dispersion (GDD), causing the pulse to be longer than originally expected, which limits the system’s peak power and temporal resolution. To achieve shorter pulse widths and higher peak intensity, high-performance dispersion compensation optical components, such as group delay interferometry (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 counteracting the dispersion introduced by the laser and other optical components, restoring the pulse’s original shape and improving overall system performance.

Since dispersion mirrors play a critical role in ultrafast lasers, they must have extremely high laser damage thresholds (LIDT) to withstand intense light, as well as excellent spectral characteristics and strictly controllable group delay dispersion parameters. The design and manufacturing process of dispersion mirrors requires a balance of high density, precise coating control, and stable layers to ensure reliable long-term operation and performance stability.

WAVEQUANTA focuses on the ultrafast optics field, dedicated to the development and production of high-quality GTI mirrors, chirped mirrors, and chirped mirror pairs. Our products not only excel in spectral response, covering a wide range of operating wavelengths, but also feature industry-leading laser damage thresholds, ensuring stable operation under high-power, ultrashort pulse conditions. By precisely controlling group delay dispersion (GDD), our dispersion mirrors help customers achieve pulse compression and control at sub-100 femtosecond or even sub-10 femtosecond levels, meeting the stringent demands of ultrafast laser technology in both fundamental research and industrial applications.

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

Precautions: For optimal performance, it is recommended to store and use the product in an environment with a temperature of 25°C and a relative humidity of 40%-60%. If the mirror surface becomes contaminated, gently wipe it with alcohol (99% or higher) and lint-free lens cleaning paper. Avoid using rough fabrics, water, or cleaning agents containing abrasive particles to prevent damaging the coating.
