In the future, an investigation to the spectral obtain curve of Yb:KGW in the key amplifier will likely be performed beneath cryogenic temperature evolution from 77 K to three hundred K. The Doing the job temperature will probably be managed to comprehend broader get bandwidth and fewer change with the central wavelength of the leading amplifier.
The crimson-shifted part of the SC is of simple importance, specifically for what considerations the general performance of broadly tunable optical parametric amplifiers pumped by the fundamental harmonics of Yb lasers. The shortage of seed photons inside the extended-wavelength region on the SC spectrum boundaries the amplification efficiency and ends in pulse-to-pulse Electrical power fluctuations throughout the degeneracy area of the optical parametric amplifier. This part is quantified in Fig. 6a by plotting the SC spectra concerning spectral Power density, which was approximated by measuring the Electricity in the axial Element of SC radiation (that's the sole nearly helpful Portion of SC emission). KGW crystal generates the highest spectral Power density in the 1200�?450 nm vary, as pointed out inside a current study30.
The datasets employed and/or analysed in the course of The present research readily available within the corresponding creator on acceptable request.
In advance of the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It absolutely was actually Utilized in the initial repeatedly operating crystal laser.
Another was placed with its Np -axis parallel While using the s-polarized path. A comparison was made concerning a configuration Along with the crystals placed in precisely the same orientation (
Comparison of spectral Electricity densities of supercontinua created in the circumstances of ideal pumping in the investigated materials.
The spectral measurements of filament-induced luminescence advise that KGW Crystal scintillating Houses of supplies may be easily researched employing femtosecond in close proximity to-infrared light resource by way of multiphoton excitation during the filamentation routine, which will allow simple separation of excitation and emission wavelengths and very low chance of optical damage.
