Laser Diode Beam Characterization

  • Haiyin Sun
Part of the SpringerBriefs in Physics book series (SpringerBriefs in Physics)


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.
