In the future, an investigation around the spectral obtain curve of Yb:KGW in the leading amplifier will likely be performed below cryogenic temperature evolution from 77 K to three hundred K. The Doing work temperature will probably be controlled to realize broader acquire bandwidth and fewer change with the central wavelength of the leading amplifier.
At the same time, a shorter laser wavelength may be obtained; it is feasible to operate using a quantum defect properly underneath 1%. Like a consequence, the warmth era is usually so small this partly compensates the decreased thermal conductivity.
The monoclinic crystal constructions results in a all-natural birefringence, assisting to stay away from thermally induced polarization rotation and depolarization decline.
The measured Reduce-off wavelengths at the shorter-wavelength side are in line with the final trend of blue-shifted spectral broadening about the bandgap of nonlinear materials. All the nonlinear materials developed realistic crimson-shifted spectral broadenings less than disorders of exceptional pump pulse energies, with the biggest pink-change exceeding 2000 nm calculated in GGG crystal. Our outcomes disclosed that GGG and BGO (which also had the lowest supercontinuum technology threshold) offer strong, optical damage-free of charge general performance at a laser repetition charge of two hundred kHz, suggesting that these products are good solutions to YAG and KGW for low threshold, large normal ability supercontinuum technology in the close to- and limited-wave infrared spectral ranges. We also demonstrated that scintillating properties of bulk supplies might be readily studied during the filamentation routine, by using KGW Crystal multiphoton excitation making use of around-infrared femtosecond laser pulses.
Down the road, We are going to undertake a laser seed by using a broader spectral bandwidth and apply an acousto-optical programmable dispersive filter to modulate the seed’s spectrum for making comprehensive use with the acquire bandwidth of our regenerative amplifier.
Comparison of spectral Electrical power densities of supercontinua produced from the disorders of exceptional pumping in the investigated supplies.
Hence, with a further advancement within our regenerative amplifier, 2 mJ compressed pulses can be envisioned, with no harming any element inside our compressor.

While BGO, GGG, YSO, LSO and LYSO from time to time serve as laser hosts37, they are largely identified as productive scintillators, whose scintillation Qualities are analyzed quite well38. Even so, the nonlinear optical Attributes of these crystals and so their prospective to function nonlinear components for SC era especially, and any other experiments concerning nonlinear propagation of extreme femtosecond laser pulses, continue being pretty improperly examined. To this point, GGG, LT23,twenty five and YSO24 were being only sketchily analyzed for SC era with Ti:sapphire laser pumping, on the other hand, to the most beneficial of our knowledge, Not one of the investigated materials were examined with Yb-laser pumping, specifically for what worries their effectiveness at quite large (tens to numerous kHz) pulse repetition prices.
