In its elemental kind, potassium has a silvery grey metallic overall look, but its compounds (such as potassium hydroxide) are more often used in industrial and chemical purposes.
-switched manner. The bandwidth from the orthogonal orientation was Plainly A great deal broader. The calculated Fourier transform limited pulse period was as brief as sub-one hundred sixty fs. Beneath the configuration where by the two crystals ended up placed in exactly the same orientation, Along with the seed enter, the amplified pulse bandwidth was only three nm with one hundred eighty μJ Power when it broke the dichroic mirrors.
The comparison with glasses is appropriate For the reason that substantial attain bandwidth enables e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.

KGW (potassium gadolinium tungstate) is actually a crystal that is commonly made use of for a Raman crystal in Raman spectroscopy. This is a colorless, transparent crystal that has a large Raman scattering efficiency and a robust Raman spectrum, which makes it ideal for A selection of Raman applications.
The spectral measurements of filament-induced luminescence counsel that scintillating Houses of resources may be conveniently analyzed employing femtosecond close to-infrared mild supply by means of multiphoton excitation inside the filamentation regime, which will allow uncomplicated separation of excitation and emission wavelengths and lower danger of optical hurt.
The two-pump laser could offer around one hundred twenty W power. Roughly sixty% of the utmost pump power was applied in our experiment contemplating the reduced overall performance from the dichroic mirrors. Less than this twin-crystal configuration, our cavity supports a a hundred W pump electric power enter, as discussed in Part 2.2. Higher-high quality dichroic mirrors will probably be used Down the road, and check here laser pulses is going to be stretched to a longer pulse length.
The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The enter of the stretcher (incident angle: 52°) and that of your compressor incident for the grating have been within the similar aspect; consequently, a slight angular tuning in the grating may very well be built to obtain the best compression end result. Within the compressor, the input angle to the grating and the gap involving the interpretation phase (S1) plus the transmission grating (TG) ended up intended to compensate for your stretcher dispersion and all dispersion released because of the elements.
