In conclusion, we shown that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are efficient nonlinear components for broadband SC era during the around-infrared and brief-wave infrared spectral ranges, when pumped by one hundred eighty fs essential harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO produced two octave-spanning SC spectra, which Assess to SC spectra developed in YAG. These products show fairly comparable performances to YAG also regarding threshold and best pump pulse energies for SC technology. Having said that, for what fears the likelihood to function at significant laser pulse repetition amount, YSO, LSO and LYSO demonstrate durable Procedure only at 10 kHz and speedily degrade (in a few minutes) at 20 kHz. In addition to the reasonably very low SC technology threshold (169 nJ), GGG demonstrated fantastic functionality attributes during the shorter-wave infrared While using the exceptional pump pulse Electricity of 464 nJ, and that is two periods decrease than in YAG: the most important pink-shifted spectral broadening and the best spectral Electricity density, outperforming KGW and YAG crystals in that part.
Its pump laser desires a brief pulse length, a reduced time jitter, and smooth temporal and spatial distributions because of the intrinsic instantaneous system. Hence, the OPCPA process is a lot more challenging and highly-priced.
For tungstates, the ytterbium doping focus can be extremely superior devoid of considerable quenching because the changed ions have a really related ion radius, and also the inter-ion length is relatively big.
Quite a few approaches are adopted to solve this issue. An acousto-optical programmable dispersive filter may be used to modulate the seed’s spectrum to suppress the gain-narrowing outcome[
The black line denotes the configuration Using the crystals positioned in a similar orientation, when the crimson line is beneath the configuration of crystals positioned in orthogonal orientation.
Thermal outcomes are appreciably more compact in KGW. This combined with the significant problems threshold make the crystal a superb applicant for ability scaling. Evaluating Ba(NO3)two and KGW for Raman software Ba(NO3)two are more practical in more info the event of ns pulses and KGW �?in the event of ps pulses.
Meanwhile, to make certain ongoing guidance, we've been exhibiting the internet site with out types and JavaScript.
