In its elemental kind, potassium incorporates a silvery gray metallic physical appearance, but its compounds (for example potassium hydroxide) are more routinely Employed in industrial and chemical programs.

The measured Lower-off wavelengths at the short-wavelength facet are in keeping with the final craze of blue-shifted spectral broadening within the bandgap of nonlinear product. The many nonlinear components manufactured sensible pink-shifted spectral broadenings beneath circumstances of exceptional pump pulse energies, with the largest purple-shift exceeding 2000 nm calculated in GGG crystal. Our final results disclosed that GGG and BGO (which also had the lowest supercontinuum technology threshold) offer sturdy, optical hurt-totally free effectiveness at a laser repetition fee of 200 kHz, suggesting that these resources are good choices to YAG and KGW for small threshold, higher common electric power supercontinuum generation inside the in close proximity to- and small-wave infrared spectral ranges. We also demonstrated that scintillating Attributes of bulk materials may be readily examined from the filamentation regime, by using multiphoton excitation using near-infrared femtosecond laser pulses.

KGW (potassium gadolinium tungstate) can be a crystal that is commonly employed like a Raman crystal in Raman spectroscopy. This is a colorless, transparent crystal which has a large Raman scattering efficiency and a powerful Raman spectrum, making it suitable for A variety of Raman apps.
The particular spectra have been reconstructed by correcting the calculated spectra using an account for that filter transmission features and for your sensitivity features with the spectrometers at the data post-processing stage. The spectral dynamics in Every sample was calculated by wonderful tuning the pump pulse Power with a pc-managed attenuator that was built-in within the laser procedure. Thermal Vitality meter EM (Ophir 3A-PF-twelve) was used to measure the SC Strength which was thereafter utilized to determine the spectral Electricity density from the SC radiation. The many measurements were carried out with none translation of the sample with respect on the pump beam.

Both of those energies are marked from the dashed strains and their values are labeled during the plots. The identical options have click here been also noticed in KGW and YAG crystals, whose spectral broadening dynamics are proven for a comparison in Fig. 4.
