An ultrafast mirror is a high-performance optical component designed for rapid, minute angular beam deflection. Operates at very high frequencies with ultra-high precision. The core function is to efficiently reflect the laser while avoiding distortion, broadening or energy loss of the laser pulse due to the characteristics of the components, thus ensuring that the "ultra-short pulse" core advantage of the ultrafast laser is not compromised.
Extremely high speed and bandwidth: Enables exceptionally fast response.
Excellent stability: Achieved via closed-loop control.
Limited deflection angle: Unsuitable for large-angle scanning.
