The Zeeman effect in the 7 F 6 5 D 4 absorption band of the Tb 3+ ion in the paramagnetic garnets Tb 3 Ga 5 O 12 and Tb 3 Al 5 O 12 was studied. The field dependences of the Zeeman splitting of some absorption lines are found to exhibit unusual behav

We studied mutual injection locking of two individual continuous-wave Nd:YVO/sub 4/ lasers that were coupled through an external section. The two lasers lased at the same wavelength with a stable output power and interference fringes with high contra

We report the solid-state synthesis, growth, and spectroscopic properties of single-crystal NaBi(WO4)2 containing Yb3+ ions. The tetragonal crystal phase is disordered, resulting in substantial inhomogeneous broadening of spectra. The site symmetry f
