Abstract
The homogeneous width of Z3 exciton absorption spectra in CuCl microcrystals was measured for the first time. It was determined to be 0.18+0.03−0.05 meV at 77 K by laser saturation spectroscopy. The temperature dependence of the Z3 exciton absorption linewidth also supported the result. The measurements of the saturation power density, the homogeneous linewidth, and the lifetime of Z3 excitons informed us of the transition dipole moment for a CuCl microcrystal. The obtained transition dipole moment for a CuCl microcrystal is about 13 times that for a unit cell in bulk CuCl.Keywords
