“…The DSR spectrum for this thickness and B ≈ 2.15 kG is presented in Fig.4. In these conditions the transition peaks become broader, but the linewidth γ DSR ≈ 380 MHz still does not exceed ∼ 500 MHz transition width obtained with 1 mm-long Rb cell [18]. Noteworthy, the F g = 1 → F e = 1 transition well seen in DSR spectrum, but hardly at all in the reference trace.…”

“…In this case the splitting of transitions is described by the projections m J and m I [13][14][15][16][17][18]. At B > 6000 G, sixteen transitions are observable in the absorption spectrum: by 8 starting from the ground states 6S 1/2 ,m J =-1/2 and and 6S 1/2 ,m J =+1/2.…”

Magnetic field-induced giant modification of probabilities for seven components of 6S 1/2 (F g =3)  6P 3/2 (F e =5) transition of Cs D 2 line forbidden by selection rules is observed experimentally for the first time. For the case of excitation with circularly-polarized laser radiation, the probability of F g =3,m F =-3  F e =5,m F =-2 transition becomes the largest among 25 transitions of F g =3  F e =2,3,4,5 group in a wide range of magnetic field 200 -3200 G. Moreover, the modification is the largest among D 2 lines of alkali metals. A half-wave-thick cell (length along the beam propagation axis L=426 nm) filled with Cs has been used in order to achieve subDoppler resolution which allows for separating the large number of atomic transitions that appear in the absorption spectrum when an external magnetic field is applied. For B > 3 kG the group of seven transitions Fg=3  Fe=5 is completely resolved and is located at the high frequency wing of Fg=3 Fe=2,3,4 transitions. The applied theoretical model very well describes the experimental curves.

“…282 Laser cooling of atoms, developed in the late 1970s and 1980s, has led to substantial improvements in the performance of atomic clocks and underlies most primary frequency standards in leading national metrology labs. By cooling atoms to microkelvin temperatures using optical fields, the mean velocity of neutral atoms can be reduced to $1 cm/s or below.…”
