Abstract

An apparatus for additively manufacturing three-dimensional objects includes a laser beam source configured to generate a laser beam, and a modulation device disposed downstream from the laser beam source. The modulation device includes a dichroic layer and a modulation layer. The dichroic layer is configured to transmit a first wavelength range of the laser beam and a second wavelength range of the laser beam to the modulation layer and reject wavelengths of the laser beam falling outside the first and second wavelength ranges where the first wavelength range is a multiple of the second wavelength range. One or more optical devices are disposed downstream of the modulation device and configured to selectively scan the laser beam onto a build plane.
