In various embodiments, wavelength beam combining laser systems incorporate etalons to establish external lasing cavities and/or to combine multiple input beams into a single output beam.

Wavelength beam combining laser systems utilizing etalons

In a calibrating method for a filter color measuring device that includes at least three color channels, a calibration matrix for transforming output signals of the color channels into tristimulus color values is formed. The calibration is performed spectrally, wherein the spectral sensitivities of the color channels of the color measuring device and the spectral emission properties of typical light sources are measured and stored, and the calibration matrix is calculated from the spectral sensitivities and the spectral emission properties of the light sources and the spectral evaluation functions of the standard observer, e.g., according to CIE 1931.
