11. FWHM 1/() is strictly valid only for a Lorentzian line shape.
12. Note that B B k B T. Thereby, magnetic field induced hole spin polarization is negligible small.
13. At very low laser intensities, the electrical noise of our 80 MHz New Focus balanced receiver becomes much larger than the optical shot noise, i.e., an optimized low noise (low frequency) balanced receiver would be advantageous for single QD SN spectroscopy.
