We employed a transmission grating (TG) as a dispersive ingredient in our stretcher and compressor. A compact configuration was adopted, the place the stretcher as well as the compressor shared just one grating much like that in Ref.
In its elemental sort, potassium has a silvery gray metallic appearance, but its compounds (for example potassium hydroxide) tend to be more usually used in industrial and chemical apps.
-switched method. The bandwidth in the orthogonal orientation was Obviously Significantly broader. The calculated Fourier remodel confined pulse duration was as brief as sub-160 fs. Underneath the configuration where by The 2 crystals had been positioned in precisely the same orientation, Along with the seed input, the amplified pulse bandwidth was only three nm with 180 μJ Vitality when it broke the dichroic mirrors.
The comparison with Eyeglasses is suitable Considering that the big get bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
SEMI EL venture is a global provider of components, devices, spare elements and materials to the semiconductor industry.
KGW (potassium gadolinium tungstate) is often a crystal that is often utilized like a Raman crystal in Raman spectroscopy. It is a colorless, clear crystal which has a high Raman scattering efficiency and a strong Raman spectrum, rendering it appropriate for a range of Raman apps.
The spectral measurements of filament-induced luminescence counsel more info that scintillating Attributes of elements might be commonly analyzed employing femtosecond near-infrared mild source by way of multiphoton excitation within the filamentation regime, which allows effortless separation of excitation and emission wavelengths and reduced possibility of optical harm.
The threshold Vitality for SC technology (hbox E _ textrm th ) was outlined since the pump pulse Power, where by the blue-shifted spectral broadening rapidly settles to a certain Slash-off wavelength That continues to be Virtually continual Despite additional increase from the pump pulse Power. The optimum energy (hbox E _textrm choose ), was outlined given that the pump pulse Strength, which provides the most important purple-shifted spectral broadening ahead of the onset of periodic modulation while in the SC spectrum due to filament refocusing.

Tungstates have a tendency to obtain higher Raman coefficients (�?Raman scattering). Thus, they are able to crank out significant Raman attain at moderate optical intensities. It is feasible to make use of the laser crystal alone as a Raman converter.
Determine 4 Beam radius variation on the two crystals even though modifying the focal length with the thermal lensing impact.
