Self-pumped phase conjugation induced by an incoherent beam
Optics Letters
|October 6, 2009
Abstract:
An incoherent beam was used to induce the self-pumped phase-conjugate output in a (BaSr) TiO(3) crystal. It was found that, in terms of the alteration of the signal-beam parameters, the induced self-pumped phase-conjugate output could be eliminated or maintained after the incoherent beam was removed. The observed effects were attributed to the local modification of the fanning geometry of the signal beam.

01:12Double Resonance Techniques: Overview
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.

01:14Phase II Conjugation Reactions: Overview
Conjugation, a key component of phase II biotransformation reactions, is a vital process in drug detoxification. It involves transferring endogenous substances like glucuronic acid, sulfate, and glycine to drugs or their metabolites formed in phase I reactions. These conjugation reactions, often catalyzed by specific enzymes, transform potentially harmful metabolites into inactive, water-soluble forms easily excreted in urine or bile. By enhancing polarity and eliminating pharmacological...
