A2B2-type push-pull porphyrins as reverse saturable and saturable absorbers.
A(2)B(2)-type push-pull porphyrins with a strong intramolecular dipole moment have been prepared via Heck and Suzuki coupling reactions as novel materials for use in nonlinear optics (NLO); they display saturable (SA) and reverse saturable absorption (RSA) properties at 532 nm and their nonlinear optical response is characterized by RSA occurring at lower intensity levels whereas the onset of S...
متن کاملExponential function for calculating saturable enzyme kinetics.
Enzyme kinetics are usually described by the Michaelis-Menten equation, where the time-dependent decrease of substrate (-dS/dt) is a hyperbolic function of maximal velocity (Vmax), Michaelis constant (Km), and amount of substrate (S). Because the Michaelis-Menten function in its most general meaning requires an assumption of steady-state, it is less curvilinear than true enzyme kinetics. A satu...
متن کاملEnhanced reverse saturable absorption in graphene/Ag2S organic glasses.
G/Ag2S composites were synthesized for the first time by a hydrothermal method. X-ray diffraction, scanning electron microscopy, and transmission electron microscopy analysis demonstrated that Ag2S nanoparticles with a diameter of about 130 nm uniformly covered the graphene surfaces. G/Ag2S composites were dispersed in methyl methacrylate (MMA), polymerized at 75 °C for 30-35 min, and finally d...
متن کاملNanosecond reverse saturable absorption in cubanelike transition-metal clusters
We report the measurement of reverse saturable absorption in four cubanelike transition-metal clusters with nanosecond laser pulses. We also present a five-level rate-equation model in which ionization and germinate recombination are included. A comparison between the model and the measured data shows that the population of the triplet states is generated mainly through the ionization–recombina...
متن کاملStability analysis of a laser with two modulated saturable absorbers
The stability analysis of a model for a laser system with two modulated saturable absorbers, each one modulated at a different frequency, is performed. The model is based on four equations describing the temporal evolution of the photon flux, the population inversion in the active media, and the saturation coefficients of each saturable absorber. The system dynamics is discussed in order to fin...
