“…I), shows that F j centers aligned along the directions (11 and ( 2 ) contribute of identical form for the MCD. The same condition applies for defects oriented along the directions (3,4,5,6). Therefore, from the MCD band absorption measurements and with a partially aligned Ff center, it is possible to calculate the true M C D contribution of the ( x ) and (JJ) transitions for both groups of defects.…”

“…A decade ago, Gellerman et al [4,5] developed a new way to produce very stable electron traps which allows to obtains a Flcenter system with complete elim'inatioii of perturbing and unwanted optical transitions of other defects in the wavelength range of interest. The technique was successfully used for KC1 crystal doped with O H -and SH-.…”

The magnetic circular dichroism (MCD) of F 2+ centers in KCI:SH− has been measured in absorption in the 1sσg → 2pyπu transitions at 493 and 509 nm, with fields up to 5 T and in the temperature range 1.5 K < T < 77 K. Within the limit of detection, no MCD is observed in the near infrared transition 1ss̀g → 2ps̀u as well as in both emissions 2pσu → Iss̀g and 2ps̀g. The optical detection of EPR in the F 2+ ground state presents an isotropic single band with g = 1.965 ± 0.007. The spin‐lattice relaxation measured at H = 0.32 T is typical of a direct process T−1 = 4.3 × 10−2 coth (gμBH/2kBT). The spectral variation of the MCD is calculated using perturbation theory to first order. The Hamiltonian includes the spin‐orbit interaction in the 2pπu excited state and the orbital molecular wave functions are obtained by a linear combination of 1s and 2p atomic orbitals. The calculated MCD is in good agreement with the observed one, for the spin‐orbit interaction strength σz = 3.6 meV.

“…Some successful electrolytic colorations used sodium fluoride [1], sodium chloride and potassium chloride [2] crystals mainly benefited the substantial elimination of the hydroxyl impurities or the hydroxyl-free. As is well known, the hydroxyl-doped sodium chloride crystal is an excellent lasing host for obtaining stable (F 2 + ) H center lasers [3]. Unfortunately, no electrolytic coloration for the sodium chloride crystals doped or contaminated with the hydroxyl impurities has been successfully performed heretofore.…”

“…Pure or doped sodium chloride crystal with color centers is a very good optoelectronic material for lasers [1], optical storage [2], etc., especially to a colored hydroxyl-doped sodium chloride crystal. The hydroxyl-doped sodium chloride crystal can be colored by additive coloration and g-ray irradiation and so on.…”
