A krypton fluoride laser (KrF laser) is a particular type of excimer laser, [1] which is sometimes (more correctly) called an exciplex laser. With its 248 nanometer wavelength, it is a deep ultraviolet laser which is commonly used in the production of semiconductor integrated circuits , industrial micromachining, and scientific research.
FROG is simply a spectrally resolved autocorrelation, which allows the use of a phase-retrieval algorithm to retrieve the precise pulse intensity and phase vs. time. It can measure both very simple and very complex ultrashort laser pulses, and it has measured the most complex pulse ever measured without the use of a reference pulse.
Rainmaking is a simple scam in which the trickster promises to use their power or influence over a complex system to make it do something favourable for the mark. Classically this was promising to make it rain, [ 91 ] but more modern examples include getting someone's app "featured" on an app store , obtaining pass marks in a university ...
While most junk email can seem like a minor annoyance, certain types of email can cause problems for not only you but other people you email. Sometimes these emails can contain dangerous viruses or malware that can infect your computer by downloading attached software, screensavers, photos, or offers for free products.
In optical physics, laser detuning is the tuning of a laser to a frequency that is slightly off from a quantum system's resonant frequency. When used as a noun, the laser detuning is the difference between the resonance frequency of the system and the laser's optical frequency (or wavelength ).
The power beaming system uses a laser running from a power supply.To define the beam size at its destination, the laser's light can be shaped by a set of optics.This light energy can be sent through air or the vacuum of space, onto a photovoltaic (PV) receiver, where it is converted back into electricity.
