In a surface plasmon resonant (SPR) configuration, real part in refraction coefficient of modulation layer material is monotonic with resonant wave length, while imaginary part is monotonic with resonant magnitude. Ba...
Recently more attention has been paid to the study of lasing without population inver-sion. It has been found that many schemes, with the help of optical coherence or quantuminterference effect, may establish such opt...

Optical and microwave devices with nonlinear materials offer a series of novel phenomena and have many potential applications, so they have received more and more attention. There have been many papers which investiga...
Synchronous fluorometry can cause a band-narrowing effect to improving the fluorometric selectivity (Fig. 1). However, since the △λ value selected is usually small (generally about 0—5 nm) in synchronous scanning, ...
1 Introduction Thousands of energy levels of uranium atom are being found, but it is difficult to identify and assign them because of the complicatedness of UI spectrum. Most of the information about the uranium atom ...
Ⅰ. INTRODUCTION Since the ionizing potential of uranium is 49958 cm-1, at least three photons of wavelengths in visible region are required to ionize an uranium atom from its ground state or one of the low...
The transmission process of radiation in absorbing medium is a multiple process of alternate absorbing and reemitting, i. e. a light pulse injected into the medium undergoes a series of absorption and reemitfing proce...
Ⅰ. INTRODUCTION The two-step photoionization process may be used in realization of isotope separation for most elements. But, the research effort on this topic has not been sufficient. To our knowledge, Karlov’s pap...
