Although ytterbium-doped laser attain media generally show a little quantum defect, ytterbium-doped tungstates permit for specifically compact values. As an example, a 1030-nm Yb:YAG laser would Usually be pumped all-around 940 nm, whereas Yb:KGW or Yb:KYW could possibly be most proficiently pumped all-around 981 nm.
The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly substantial compared with that of Yb:YAG. This permits for huge wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values perfectly under a hundred fs are already achieved with passive method locking.
In its elemental variety, potassium provides a silvery grey metallic overall look, but its compounds (which include potassium hydroxide) are more frequently Utilized in industrial and chemical applications.
The datasets made use of and/or analysed for the duration of The existing examine accessible through the corresponding author on realistic request.
The calculated cut-off wavelengths in the limited-wavelength side are consistent with the final trend of blue-shifted spectral broadening around the bandgap of nonlinear substance. All of the nonlinear products created fair red-shifted spectral broadenings below circumstances of optimum pump pulse energies, with the largest pink-shift exceeding 2000 nm measured in GGG crystal. Our results unveiled that GGG and BGO (which also experienced the lowest supercontinuum technology threshold) offer here you durable, optical hurt-no cost performance in a laser repetition fee of 200 kHz, suggesting that these elements are excellent alternatives to YAG and KGW for minimal threshold, large typical electric power supercontinuum technology during the near- and short-wave infrared spectral ranges. We also demonstrated that scintillating Homes of bulk supplies may very well be easily researched while in the filamentation routine, by using multiphoton excitation employing in close proximity to-infrared femtosecond laser pulses.

KGW has a solid Raman spectrum that extends in the ultraviolet on the in close proximity to infrared, rendering it handy for A selection of apps. The crystal can be utilized being a reference product for Raman spectroscopy, in addition to a sample for learning Raman scattering inside the strong point out.
