The very first two peaks can be associated with luminescence of pure material59, when the remaining peaks may very well be attributed on the luminescence of unidentified dopants, Even though the supplier specified the sample as undoped. The luminescence of YAG crystal generates sturdy UV luminescence with a maximum depth at 300 nm, which can be attributed to combined self-trapped exciton and antisite defect-linked emissions60. Last but not least, no luminescence in the UV, seen and in close proximity to-IR was noticed in KGW and LT crystals, not less than in the detection range of fiber spectrometer (200�?00 nm).
Its pump laser needs a short pulse duration, a reduced time jitter, and smooth temporal and spatial distributions because of the intrinsic instantaneous system. As a result, the OPCPA program is a lot more challenging and expensive.
For tungstates, the ytterbium doping focus can be quite substantial with no important quenching as the changed ions have an exceedingly identical ion radius, as well as inter-ion distance is fairly large.
A number of strategies are actually adopted to solve this problem. An acousto-optical programmable dispersive filter might be used to modulate the seed’s spectrum to suppress the attain-narrowing outcome[
In its elemental variety, gadolinium features a silvery-white visual appearance. Gadolinium is usually a uncommon earth or lanthanide element that possesses special Houses useful to specialised purposes like semiconductor fabrication and nuclear reactor shielding. It is actually used for both equally its superior magnetic moment (7.ninety fourμ B) and in phosphors and scintillator crystals. When complexed with EDTA ligands, it is utilised being an injectable distinction agent for MRIs. The factor is named following the Finnish chemist and geologist Johan Gadolin.
The actual spectra were being reconstructed by correcting the measured spectra with an account for your filter transmission functions and for that sensitivity features of the spectrometers at the info submit-processing phase. The spectral dynamics in Each and every sample was measured by high-quality tuning the pump pulse Power with a pc-managed attenuator which was built-in from the laser procedure. Thermal Power meter EM (Ophir 3A-PF-12) was used to measure the SC Electricity which was thereafter accustomed to estimate the spectral energy density in the SC radiation. Each of the measurements have been performed with no translation of the sample with regard towards the pump beam.
The two-pump laser could supply approximately a hundred and twenty W power. Around sixty% of the most pump electric power was utilized in our experiment thinking about the lower effectiveness with the dichroic mirrors. Less than this twin-crystal configuration, our cavity supports a one hundred W pump electricity enter, as talked over in Portion two.two. Substantial-good quality dichroic mirrors might be utilised Later on, and laser pulses will likely be stretched to a longer pulse period.
Even though BGO, GGG, YSO, LSO and LYSO occasionally function laser hosts37, They're generally recognized as efficient scintillators, whose scintillation Homes are examined fairly well38. On the other hand, the nonlinear optical Homes of these crystals and so their likely to function nonlinear supplies for SC era especially, and every other experiments relating to nonlinear propagation of intense femtosecond laser pulses, stay quite improperly studied. Up to now, GGG, LT23,twenty five and YSO24 ended up only sketchily tested for SC generation with Ti:sapphire laser pumping, nonetheless, to the most beneficial of our knowledge, Not one of the investigated components were examined with Yb-laser pumping, especially for what problems their overall performance at really significant (tens to hundreds of kHz) pulse repetition prices.
The Yb:KGW laser program provides a quasi-a few-level conduct. The web get of your Yb:KGW crystal wasn't read more substantial: quite a few tens of roundtrips were needed to amplify the nanojoule seed into a millijoule stage. Consequently, the attain-narrowing effect was inevitable in Yb:KGW regenerative amplifiers.
