In this study, a method is proposed to measure the spatial properties of laser emissions in the range of 2.0 µm. The infrared emission spectrum is first converted into a spectrum in the visible range using a fluorozirconate ZBLAN:Ho3+ glass sample. Subsequently, the converted emission is detected using a Pulnix TM-7CN CCD camera and the laser beam image is numerically processed using a specialized software package in the LabVIEW environment. This enables the measurement of intensity distribution over the beam cross-section of the diode-pumped CW YAP:Tm3+ laser emitting at 1.94 µm. The beam quality factor, M2, is also evaluated.
