Quantum cascade lasers (QCLs) are a candidate for calibration sources in space-based remote sensing applications. However, the output beam from a QCL has some characteristics that are undesirable in a calibration source. The output beam from a QCL is polarized both temporally and spatially coherent, and has a non-uniform bivariate Gaussian profile. These characteristics need to be mitigated before QCLs can be used as calibration sources. This study presents the design and implementation of an optical system that manipulates the output beam from a QCL so that it is spatially and angularly uniform with reduced coherence and polarization.
