The thermal conductivity of typical double tungstates is of your get to 3–four W/(K m) �?which is not negative when compared with other laser crystals (Despite the fact that numerous situations fewer than for YAG), and reasonably huge compared While using the thermal conductivity of regular glasses.

For a few apps, tungstates provide a mix of various useful properties. Specifically for passive method locking, ytterbium-doped double tungstates in many cases are outstanding to other media in terms of the combination of high acquire bandwidth, significant cross-sections, and comparatively good thermal Houses �?Despite the fact that in Each individual certain willpower superior supplies can be identified.

In conclusion, we demonstrated that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are successful nonlinear materials for broadband SC technology inside the in close proximity to-infrared and shorter-wave infrared spectral ranges, when pumped by one hundred eighty fs essential harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO manufactured two octave-spanning SC spectra, which Evaluate to SC spectra developed in YAG. These resources exhibit really very similar performances to YAG also with regard to threshold and best pump pulse energies for SC technology. Nonetheless, for what concerns the chance to work at high laser pulse repetition rate, YSO, LSO and LYSO demonstrate durable operation only at ten kHz and quickly degrade (inside a couple of minutes) at twenty kHz. Moreover the comparatively lower SC era threshold (169 nJ), GGG demonstrated wonderful performance qualities from the limited-wave infrared With all the ideal pump pulse Strength of 464 nJ, that's two occasions decreased than in YAG: the biggest purple-shifted spectral broadening and the highest spectral Vitality density, outperforming KGW and YAG crystals in that aspect.

-switched method. The bandwidth while in the orthogonal orientation was Evidently Substantially broader. The calculated Fourier completely transform confined pulse period was as quick as sub-160 fs. Beneath the configuration where by the two crystals had been put in the exact same orientation, While using the seed enter, the amplified pulse bandwidth was only 3 nm with one hundred eighty μJ energy when it broke the dichroic mirrors.

The calculated cut-off wavelengths for the brief-wavelength aspect are according to the final trend of blue-shifted spectral broadening within the bandgap of nonlinear material. The many nonlinear elements generated sensible purple-shifted spectral broadenings beneath disorders of best pump pulse energies, with the most important red-change exceeding 2000 nm measured in GGG crystal. Our final results discovered that GGG and BGO (which also experienced the bottom supercontinuum era threshold) offer you tough, optical destruction-totally free general performance in a laser repetition rate of two hundred kHz, suggesting that these supplies are great solutions to YAG and KGW for very low threshold, significant average energy supercontinuum generation within the close to- and short-wave infrared spectral ranges. We also demonstrated that scintillating Houses of bulk components might be conveniently researched inside the filamentation routine, via multiphoton excitation employing in the vicinity of-infrared femtosecond laser pulses.

The black line denotes the configuration With all the crystals positioned in exactly the same orientation, when the red line is beneath the configuration of crystals put in orthogonal orientation.

Thermal consequences are noticeably smaller sized in KGW. This together with the significant hurt threshold make the crystal a superb prospect for electricity scaling. Evaluating Ba(NO3)two and KGW for Raman software Ba(NO3)two are more practical in the event of ns pulses and KGW �?in the event of ps pulses.

The crimson-shifted Portion of the SC spectrum in BGO has the lowest spectral energy density, that is 1–two orders of magnitude decreased than in the rest of the supplies. Nonetheless, really minimal energy threshold of SC generation, and also very low best pump Strength in BGO, really should be identified. The approximated spectral Strength densities developed in LSO and LYSO are pretty much like YAG throughout the major Section of the SC spectrum. Quite possibly the most attention-grabbing acquiring in that regard is GGG crystal, which, despite quite moderate blue-shifted spectral broadening, generates the most important spectral pink-shift and the very best spectral Electricity density in the 1600�?000 nm assortment, which is nearly an get of magnitude bigger more info than that made in YAG.

The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The input on the stretcher (incident angle: fifty two°) Which in the compressor incident with the grating have been with the identical side; that's why, a slight angular tuning of your grating might be made to acquire the most effective compression final result. While in the compressor, the input angle over the grating and the gap in between the translation stage (S1) plus the transmission grating (TG) were being built to compensate for your stretcher dispersion and all dispersion introduced by the elements.
