Later on, an investigation around the spectral gain curve of Yb:KGW in the main amplifier will probably be executed underneath cryogenic temperature evolution from 77 K to three hundred K. The working temperature are going to be managed to appreciate broader achieve bandwidth and fewer change with the central wavelength of the leading amplifier.
In its elemental kind, potassium incorporates a silvery grey metallic appearance, but its compounds (for instance potassium hydroxide) are more often Employed in industrial and chemical programs.
The datasets used and/or analysed all through The existing research out there from your corresponding writer on acceptable ask for.
The measured Minimize-off wavelengths on the small-wavelength side are consistent with the final trend of blue-shifted spectral broadening to the bandgap of nonlinear material. Every one of the nonlinear supplies generated reasonable crimson-shifted spectral broadenings under circumstances of best pump pulse energies, with the most important purple-shift exceeding 2000 nm measured in GGG crystal. Our benefits discovered that GGG and BGO (which also experienced the lowest supercontinuum technology threshold) offer resilient, optical destruction-free performance in a laser repetition charge of two hundred kHz, suggesting that these elements are very good solutions to YAG and KGW for low threshold, higher typical energy supercontinuum technology during the close to- and shorter-wave infrared spectral ranges. We also demonstrated that scintillating Homes of bulk elements may be easily analyzed in the filamentation regime, by way of multiphoton excitation using close to-infrared femtosecond laser pulses.
Nonetheless, the moment Nd3+:YAG grew to become commercially offered, the fascination in CaWO4 dropped sharply. In later years, certain other tungstate crystals started to appeal to loads of attention.
Comparison of spectral Electrical power densities of supercontinua generated inside the conditions of best pumping within the investigated products.
Inquire RP Photonics for any guidance concerning tungstate lasers, including femtosecond lasers and superior-ability lasers.

-switched laser output beneath the two crystal placement configurations. The black line denotes the configuration Together with the crystals positioned in precisely the same orientation, even though the red line is under the configuration of crystals put in orthogonal orientation.
Figure 4 Beam radius variation on The 2 crystals though switching the focal size from the thermal lensing outcome.
The origin on the aspect's identify arises from the English phrase 'potash,' indicating pot ashes, and the Arabic word qali
