Along with its use as a Raman crystal, KGW is also Utilized in other optical applications, for instance in laser techniques and to be a scintillator in clinical imaging.
-switched manner. The bandwidth while in the orthogonal orientation was Obviously A great deal broader. The calculated Fourier rework restricted pulse length was as short as sub-one hundred sixty fs. Beneath the configuration exactly where the two crystals ended up placed in the exact same orientation, With all the seed input, the amplified pulse bandwidth was only 3 nm with one hundred eighty μJ Power when it broke the dichroic mirrors.
Amplified pulses with an energy above 2.five mJ is usually envisioned by implementing an increased pump power to the regenerative amplifier and rendering it work in the saturation degree. The laser fluence of ~1 J/cm2 about the dichroic mirrors is considered for being under the problems threshold of large-quality dielectric-coated mirrors.
The opposite was positioned with its Np -axis parallel Together with the s-polarized route. A comparison was designed between a configuration With all the crystals placed in exactly the same orientation (
KGW (potassium gadolinium tungstate) is actually a crystal that is usually utilised as being a Raman crystal in Raman spectroscopy. It's a colorless, clear crystal that has a substantial Raman scattering efficiency and a robust Raman spectrum, rendering it appropriate for A selection of Raman applications.
The actual spectra had been reconstructed by correcting the calculated spectra having an account with the filter transmission features and for the sensitivity capabilities on the spectrometers at the information submit-processing stage. The spectral dynamics in each sample was calculated by fantastic tuning the pump pulse energy with a pc-controlled attenuator that was integrated during the laser method. Thermal Strength meter EM (Ophir 3A-PF-12) was utilized to measure the SC energy which was thereafter accustomed to work out the spectral Vitality density on the SC radiation. All of the measurements ended up carried out with no translation from the sample with respect for the pump beam.
The brink energy for SC generation (hbox E _ textrm th ) was outlined because the pump pulse energy, where the blue-shifted spectral broadening rapidly settles to a specific Slice-off wavelength That continues to be click here Just about consistent Despite more boost on the pump pulse energy. The optimum Power (hbox E _textrm opt ), was described given that the pump pulse Electrical power, which creates the biggest red-shifted spectral broadening before the onset of periodic modulation during the SC spectrum resulting from filament refocusing.

-switched output spectrum in the regenerative amplifier supports a sub-a hundred and sixty fs pulse amplification. Consequently, pulses with energies of as many as two mJ and duration beneath two hundred fs is often received making use of bigger-high quality dichroic mirrors plus a broader-spectrum laser seed. This regenerative amplifier works as a great pre-amplifier for more laser amplification.
