Efficient electromagnetically induced transparency in a rare-earth doped crystal
We have observed up to 100% transmission of a probe field at line center due to electromagnetically induced transparency (EIT) in an optically dense rare-earth crystal of Pr 3+ doped YzSiOs at 5.5 K. We also have examined both laser field intensity and temperature dependence of the EIT. Efficient EIT in this crystal opens potential applications such as efficient high-resolution image processing...
متن کاملCrystal-field study in rare-earth-doped semiconducting YBiPt
Electron spin resonance ~ESR! and magnetic-susceptibility experiments in the rare-earth-doped (R5Nd, Er, and Yb! cubic semiconducting YBiPt allow estimates of the fourth (A4) and sixth (A6) order crystal-field parameters for this compound. It is found that these parameters are of the same order for all the R studied. On the other hand, no crystal-field effects were found for the Gd doped single...
متن کاملRare Earth Elements Profile
Definitions and characteristics The rare earth elements (REE) (sometimes referred to as the rare earth metals) are a group of 17 chemically similar metallic elements, including the 15 lanthanides, scandium and yttrium. The lanthanides are elements spanning atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu) (Table 1). The lanthanides all occur in nature, although promethium, the rarest, only...
متن کاملRare earth-doped glass microbarcodes.
The development of ultraminiaturized identification tags has applications in fields ranging from advanced biotechnology to security. This paper describes micrometer-sized glass barcodes containing a pattern of different fluorescent materials that are easily identified by using a UV lamp and an optical microscope. A model DNA hybridization assay using these "microbarcodes" is described. Rare ear...
متن کاملRare-Earth Doped Optical Fibers
An optical fiber becomes active by doping its core with one or more atomic elements, usually (but not restricted to) rare-earths (RE’s), more specifically, the lanthanides that occupy the atomic numbers 57 to 71 of the periodic table. As it will be mentioned later in more detail, they use three electrons in bonding to the condensed materials such as crystals and glasses to become triply ionized...
