Abstract

Digital micromirror devices (DMDs) have shown their potential in 2-photon imaging and microfabrication as a flexible scanner for femtosecond lasers. However, the resulted light beam is often constrained by dispersion due to the diffractive nature of the scanning. Here we show how to overcome these problems.
