Measuring Everything You’ve Ever Wanted to Know About an Ultrashort Light Pulse

چکیده
We review the problem of measuring an ultrashort laser pulse and then describe several experimentally simple, accurate, and very reliable methods for measuring both very simple laser pulses and very complex ultrashort light pulses. Each of these methods comprises only a few easily aligned components, and they allow the measurement of a wide range of pulses, including those with time-bandwidth products greater than 1000 and those with energies of only a few hundred photons. Finally, two recently introduced very simple methods allow the measurement of the complete spatio-temporal intensity and phase of even complex pulses on a single shot or at a tight focus. In short, pulse-measurement technology is now so powerful and easy to use that it is time to use these methods and to focus on their applications.

Nanocomposite materials, including noble metal nanoparticles embedded in a dielectric host medium, are interesting because of their optical properties linked to surface plasmon resonance phenomena. For studding of nonlinear optical properties and/or energy transfer process, these materials may be excited by ultrashort pulse laser with a temporal width varying from some femtoseconds to some hund...

Indeed, to see the action in any fast event, whether it’s a computer chip switching states, dynamite exploding, or a simple soap bubble popping, requires a strobe light with a shorter duration in order to freeze the action. But then to measure the strobe-light pulse requires a light sensor whose response time is even faster. And then to measure the light-sensor response time requires an even sh...

The mechanisms that maintain the stability of chromosome ends have broad impact on genome integrity in all eukaryotes. Budding yeast is a premier organism for telomere studies. Many fundamental concepts of telomere and telomerase function were first established in yeast and then extended to other organisms. We present a comprehensive review of yeast telomere biology that covers capping, replica...
