Abstract

Techniques for characterizing the spatial and spectral properties of single TE mode laser diode beams are described. The spatial properties include beam size and shape, waist size and location, M 2 factor, far field divergence, and astigmatism. The spectral parameters include the wavelength and linewidth. The measurement of laser power and energy is briefly touched.
