Restoration of Beam Brightness by Wavefront Measurement and Correction of a High-Brightness 2.1µm Direct-diode Laser Module

Abstract

A laser diode module at 2.1 µm is limited in brightness due to assembly errors and aberrations from off-the-shelf collimation optics. Laser-machined micro-optics can provide full correction, given new wavefront measurements at mid-IR wavelengths.
