Later on, an investigation over the spectral get curve of Yb:KGW in the principle amplifier will likely be performed under cryogenic temperature evolution from seventy seven K to 300 K. The Functioning temperature is going to be controlled to understand broader get bandwidth and fewer shift within the central wavelength of the primary amplifier.
In conclusion, we shown that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are successful nonlinear supplies for broadband SC generation while in the around-infrared and limited-wave infrared spectral ranges, when pumped by 180 fs basic harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO produced two octave-spanning SC spectra, which Evaluate to SC spectra developed in YAG. These resources show quite comparable performances to YAG also regarding threshold and best pump pulse energies for SC era. Having said that, for what fears the possibility to work at large laser pulse repetition level, YSO, LSO and LYSO demonstrate sturdy Procedure only at ten kHz and speedily degrade (in a couple of minutes) at twenty kHz. Other than the comparatively lower SC generation threshold (169 nJ), GGG demonstrated outstanding functionality properties in the small-wave infrared Using the ideal pump pulse energy of 464 nJ, which can be two periods lessen than in YAG: the largest purple-shifted spectral broadening and the highest spectral energy density, outperforming KGW and YAG crystals in that factor.
-switched mode. The bandwidth inside the orthogonal orientation was Obviously A lot broader. The calculated Fourier transform restricted pulse duration was as quick as sub-a hundred and sixty fs. Beneath the configuration the place The 2 crystals ended up placed in the exact same orientation, with the seed enter, the amplified pulse bandwidth was only three nm with 180 μJ energy when it broke the dichroic mirrors.
The calculated Minimize-off wavelengths with the small-wavelength facet are in line with the overall trend of blue-shifted spectral broadening to the bandgap of nonlinear content. Every one of the nonlinear resources developed realistic red-shifted spectral broadenings under situations of ideal pump pulse energies, with the largest pink-shift exceeding 2000 nm measured in GGG crystal. Our effects exposed that GGG and BGO (which also experienced the bottom supercontinuum generation threshold) present durable, optical injury-absolutely free effectiveness at a laser repetition amount of two hundred kHz, suggesting that these supplies are excellent choices to YAG and KGW for very low threshold, higher normal electricity supercontinuum generation during the near- and brief-wave infrared spectral ranges. We also demonstrated that scintillating properties of bulk materials can be commonly researched inside the filamentation routine, through multiphoton excitation employing in close proximity to-infrared femtosecond laser pulses.
