The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant in contrast with that of Yb:YAG. This allows for huge wavelength tunability and for Significantly shorter pulse durations from manner-locked lasers. Values nicely underneath 100 fs have already been attained with passive method locking.
The crimson-shifted Portion of the SC is of functional relevance, specifically for what worries the general performance of broadly tunable optical parametric amplifiers pumped by the elemental harmonics of Yb lasers. The dearth of seed photons inside the long-wavelength location of your SC spectrum boundaries the amplification efficiency and brings about pulse-to-pulse Strength fluctuations throughout the degeneracy area from the optical parametric amplifier. This element is quantified in Fig. 6a by plotting the SC spectra with regards to spectral Vitality density, which was approximated by measuring the Electrical power on the axial Portion of SC radiation (that is the one pretty much useful Component of SC emission). KGW crystal creates the best spectral Vitality density in the 1200�?450 nm vary, as noted in a new study30.
The datasets employed and/or analysed in the course of the current analyze offered from your corresponding author on affordable ask for.

Circumstance Scientific studies of chosen critical systems invented or co-invented by American Features in just the 1st 20 years of the century
The particular spectra have been reconstructed by correcting the calculated spectra using an account for the filter transmission features and for the sensitivity features of the spectrometers at the information post-processing stage. The spectral dynamics in each sample was measured by great tuning the pump pulse Power with a computer-managed attenuator which was integrated in the laser technique. Thermal Power meter EM (Ophir 3A-PF-twelve) was used to measure the SC Electricity which was thereafter used to compute the spectral energy density on the SC radiation. All the measurements had been carried out with none translation of the sample with respect to your pump beam.
The threshold Strength for SC generation (hbox E _ textrm th ) was outlined given that the pump pulse Vitality, where by the blue-shifted spectral broadening rapidly settles to a particular Slash-off wavelength that remains Practically constant Despite even further increase of your pump pulse energy. The ideal Electricity (hbox E _textrm decide ), was defined as the pump pulse Vitality, which generates the biggest purple-shifted spectral broadening ahead of the onset of periodic modulation during the SC spectrum due to filament refocusing.
