Although ytterbium-doped laser achieve media usually show a little quantum defect, ytterbium-doped tungstates allow for for notably smaller values. Such as, a 1030-nm Yb:YAG laser would Typically be pumped around 940 nm, Whilst Yb:KGW or Yb:KYW might be most successfully pumped all around 981 nm.
Down the road, an investigation around the spectral gain curve of Yb:KGW in the principle amplifier will be carried out underneath cryogenic temperature evolution from 77 K to 300 K. The Doing the job temperature will probably be managed to comprehend broader get bandwidth and fewer change for the central wavelength of the most crucial amplifier.
The crimson-shifted Element of the SC is of simple importance, specifically for what issues the efficiency of broadly tunable optical parametric amplifiers pumped by the basic harmonics of Yb lasers. The dearth of seed photons in the lengthy-wavelength region with the SC spectrum limits the amplification performance and leads to pulse-to-pulse Power fluctuations around the degeneracy area of your optical parametric amplifier. This factor is quantified in Fig. 6a by plotting the SC spectra when it comes to spectral Electrical power density, which was believed by measuring the Electricity of the axial Portion of SC radiation (that's the only almost valuable Section of SC emission). KGW crystal provides the very best spectral Electricity density within the 1200�?450 nm range, as noted inside of a recent study30.
The datasets made use of and/or analysed through the current examine offered through the corresponding author on fair ask for.
For tungstates, the ytterbium doping concentration can be quite large without having sizeable quenching since the replaced ions have an incredibly identical ion radius, along with the inter-ion length is comparatively massive.
SEMI EL task is a worldwide supplier of components, website tools, spare components and materials to the semiconductor industry.
KGW (potassium gadolinium tungstate) can be a crystal that is usually utilised like a Raman crystal in Raman spectroscopy. It is just a colorless, clear crystal that includes a significant Raman scattering efficiency and a strong Raman spectrum, rendering it suited to An array of Raman purposes.
Inquire RP Photonics for almost any suggestions regarding tungstate lasers, like femtosecond lasers and large-electric power lasers.
We developed a diode-pumped Yb:KGW regenerative amplifier as being the front close from the kilohertz terawatt laser system. Wide bandwidth pulses were acquired by applying twin crystals with distinct orientations in their optical axes[
These materials can be used for frequency conversion in lasers for extending of tuning vary. SRS in crystals is appropriate with latest all-sound-condition engineering and offers a very simple, compact means of frequency conversion.
-switched output spectrum from the regenerative amplifier supports a sub-160 fs pulse amplification. Therefore, pulses with energies of as much as 2 mJ and period underneath two hundred fs can be attained using higher-excellent dichroic mirrors as well as a broader-spectrum laser seed. This regenerative amplifier performs as an excellent pre-amplifier for even more laser amplification.
