Inte # Olecular Energy Transfer Stud 1 with Picosecond Light Pulses
The time deveIopment for the intermolecular transfer of electronic energy has, until recently, been studied by measurements of the molecular light emission. The observation of the transfer process has been limited to times of the order of the fluorescent lifetime, and naturally to systems which emit light $#. With the application of the picosecond method 121, which utilizes absorption, rather t...
متن کاملTime-Resolved Fluorescence Immunoassay for C-Reactive Protein Using Colloidal Semiconducting Nanoparticles
Besides the typical short-lived fluorescence with decay times in the nanosecond range, colloidal II/VI semiconductor nanoparticles dispersed in buffer also possess a long-lived fluorescence component with decay times in the microsecond range. Here, the signal intensity of the long-lived luminescence at microsecond range is shown to increase 1,000-fold for CdTe nanoparticles in PBS buffer. This ...
متن کاملPicosecond UV laser induced morphological, biochemical and biological changes in Bombyx mori
Background: In the light of various applications of UV laser in biological system, we have investigated the effect of picosecond UV laser radiation on silkworm Bombyx mori. Materials and Methods: The eggs of NB4D2 of different stages were exposed to pico second pulse laser at 355 nm from Nd:YAG laser for different durations. Results: Due to irradiation alterations in crescent larval body...
متن کاملPicosecond laser pulse generation in a monolithic self-Q-switched solid-state laser
We report the generation of laser pulses of 290-ps duration with 8-N pulse energy in single longitudinal mode and single transverse mode in a diode-end-pumped monolithic self-Q-switched Cr,Nd:YAG laser. The most commonly used method of generating picosecond laser pulses is the mode-locking technique. Mode-locking generally requires a light modulator such as an intracavity acousto-optical modula...
متن کاملPicosecond absorption relaxation measured with nanosecond laser photoacoustics.
Picosecond absorption relaxation-central to many disciplines-is typically measured by ultrafast (femtosecond or picosecond) pump-probe techniques, which however are restricted to optically thin and weakly scattering materials or require artificial sample preparation. Here, we developed a reflection-mode relaxation photoacoustic microscope based on a nanosecond laser and measured picosecond abso...
