We employed a transmission grating (TG) being a dispersive component inside our stretcher and compressor. A compact configuration was adopted, the place the stretcher as well as the compressor shared one grating comparable to that in Ref.
In summary, we demonstrated that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are successful nonlinear resources for broadband SC technology from the around-infrared and small-wave infrared spectral ranges, when pumped by 180 fs basic harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO developed two octave-spanning SC spectra, which Look at to SC spectra created in YAG. These resources show pretty similar performances to YAG also when it comes to threshold and ideal pump pulse energies for SC technology. Nonetheless, for what worries the chance to operate at large laser pulse repetition amount, YSO, LSO and LYSO show sturdy operation only at 10 kHz and quickly degrade (inside of a few minutes) at twenty kHz. Other than the relatively reduced SC generation threshold (169 nJ), GGG demonstrated excellent overall performance characteristics in the short-wave infrared Together with the optimum pump pulse Electricity of 464 nJ, and that is two times reduce than in YAG: the most important pink-shifted spectral broadening and the very best spectral energy density, outperforming KGW and YAG crystals in that aspect.
The datasets applied and/or analysed in the course of The existing research available through the corresponding writer on realistic request.
For tungstates, the ytterbium doping focus can be quite significant devoid of considerable quenching as the replaced ions have an exceedingly equivalent ion radius, as well as inter-ion length is pretty massive.

Though BGO and LT developed the narrowest SC spectra (a little bit lower than one.five optical octaves), they might be considered as check here extremely eye-catching nonlinear resources for broadband SC technology with pumping at for a longer period laser wavelengths. Owing to its substantial nonlinearity, BGO exhibited the bottom SC technology threshold (seventy eight nJ) Among the many investigated resources, which happens to be 25 % decreased than in KGW and will be regarded as superb nonlinear material for incredibly minimal-threshold SC technology. The observed steady and durable problems-no cost efficiency of BGO and GGG at 200 kHz pulse repetition amount implies that these nonlinear materials have a potential for SC generation at even larger, MHz, repetition prices. Furthermore, these materials deliver SC radiation with a wonderful list of parameters which have been important for programs in large velocity spectroscopy and imaging that make use of bulk-created SC, see e.g.seventeen,eighteen,19,twenty.

Tungstates have a tendency to obtain higher Raman coefficients (�?Raman scattering). Thus, they are able to make sizeable Raman attain at moderate optical intensities. It is feasible to make use of the laser crystal alone as a Raman converter.
