Dispersive Mirrors

Use these mirrors with dispersion-optimized coatings as key elements to control the intensity and phase of femtosecond lasers and systems over specific wavelength ranges.

Coherent is a leader in ultrafast laser technologies. We offer a full range of optics to manage group delay (GD) and group delay dispersion (GDD) at wavelengths from 350 nm to 3000 nm. These include chirped mirrors, dispersion compensation mirrors, and more.

Dispersive Mirrors – Typical Specifications Overview

Use these mirrors to enable Visible Lasers, Chirped Pulse Amplification (CPA), Optical Parametric Oscillators (OPOs), and Optical Parametric Amplifiers (OPAs)
