Wang, Xi; Zhang, Aihua; Zhi, Miaochan; Sokolov, Alexei V.; Welch, George R. (American Physical Society, 2010)We investigate the possibility of using a hybrid coherent anti-Stokes Raman scattering technique for noninvasive monitoring of blood glucose levels. Our technique combines instantaneous coherent excitation of several ...

Scully, Marlan O.; Kattawar, George W.; Lucht, Robert P.; Opatrny, Tomas; Pilloff, Herschel S.; Sokolov, Alexei V.; Zubairy, Suhail M. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2004-09-21)According to one embodiment of the present invention, identifying a molecule of a sample includes illuminating the sample with a preparation light beam, where the preparation light beam can initiate a substantially maximized ...

Burzo, Andrea Mihaela (Texas A&M University, 2007-04-25)Generation of reproducible attosecond (10-18s) pulses is an exciting goal: in the same way as femtosecond pulses were used to make "movies" of the atomic motion in molecules, attosecond pulses could "uncover" the motion ...
-
Zhu, Feng (2012-02-14)A detailed investigation of ion crystals produced by laser and sympathetic cooling in a linear RF trap has been conducted. The laser cooling methods were examined and applied to the trapped ^24Mg^(positive) ions. The ...

Hsu, Paul Steve (2009-05-15)Laser-atom interactions create atomic coherence and large nonlinear atomic polarization. We investigate resonant laser-atom interactions to generate large nonlinearities and control them using magneto-optical fields. ...
-
Wang, Jizhou (2022-07-21)Molecular spectroscopy, including Raman spectroscopy and infrared (IR) spectroscopy, is used to study the interactions between electromagnetic fields and molecules. The measured spectrum can provide information on molecular ...

Novikova, Irina Borisovna (Texas A&M University, 2004-09-30)Nonlinear magneto-optical effects, originated from atomic coherence, are studied both theoretically and experimentally in thermal Rb vapor. The analytical description of the fundamental properties of coherent media are ...
-
Talib, Ansam Jameel (2018-05-04)Upconversion nanoparticles (UCNPs) are popular fluorescent probes for biological systems because of their immunity to autofluorescence background, photostability, and low toxicity. Nanodiamonds are also of interest for ...

Observation of precursorlike behavior of femtosecond pulses in a dye with a strong absorption band Springer, Matthew M.; Yang, Wenlong; Kolomenski, Alexandre A.; Schuessler, Hans A.; Strohaber, James; Kattawar, George W.; Sokolov, Alexei V. (American Physical Society, 2011)Recent interest in Sommerfeld-Brillouin optical precursors has brought attention to the possibility of optical precursor observation in bulk matter. We investigate the possible formation of optical precursors in an organic ...

Li, Hebin; Sautenkov, Vladimir A.; Kash, Michael M.; Sokolov, Alexei V.; Welch, George R.; Rostovtsev, Yuri V.; Zubairy, M. Suhail; Scully, Marlan O. (American Physical Society, 2008)We study the possibility of creating spatial patterns having subwavelength size by using the so-called dark states formed by the interaction between atoms and optical fields. These optical fields have a specified spatial ...
