12.7mm Dia., 650 – 1350nm, Complementary Chirped Mirror Pair

Product Details Ideal for Chirped-Pulse Amplifier Systems and Ultra-Broadband Laser Oscillators Ultra-Broadband Design Supports Dispersion Compensation Negative GDD as Low as -60fs 2 and High Reflectivity (>99%) at 600 – 950nm or 650 – 1350nm UltraFast Innovations (UFI) Ultra-Broadband Complementary Chirped Mirror Pairs are designed to provide dispersion compensation for ultrafast pulses. The matched mirrors feature out-of-phase group delay dispersion (GDD) oscillations leading to a near-constant GDD performance with minimal oscillations. The broadband coating design covers the most common ultrafast laser lines, including Ti:sapphire and Yb:doped fiber, providing negative GDDs as low as -60fs 2 and average reflectance of >99% (p-polarization) at 600 – 950nm or 650 – 1350nm. The narrow angles of incidence (AOI) allows many reflections of the ultrafast pulse to effectively compensate for dispersion effects. UFI Ultra-Broadband Complementary Chirped Mirror Pairs are ideal for dispersion compensation in ultrafast laser applications, including chirped-pulse amplifier systems and ultra-broadband laser oscillators.
