While ytterbium-doped laser acquire media typically show a little quantum defect, ytterbium-doped tungstates allow for for significantly tiny values. Such as, a 1030-nm Yb:YAG laser would Generally be pumped all over 940 nm, While Yb:KGW or Yb:KYW may be most competently pumped around 981 nm.

A not-for-gain Corporation, IEEE is the entire world's premier complex Specialist Group focused on advancing know-how for the advantage of humanity.

In summary, we shown that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are efficient nonlinear supplies for broadband SC generation while in the around-infrared and limited-wave infrared spectral ranges, when pumped by a hundred and eighty fs fundamental harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO created two octave-spanning SC spectra, which Assess to SC spectra produced in YAG. These resources show fairly very similar performances to YAG also when it comes to threshold and ideal pump pulse energies for SC era. However, for what concerns the possibility to function at substantial laser pulse repetition fee, YSO, LSO and LYSO clearly show resilient Procedure only at ten kHz and immediately degrade (inside a few minutes) at twenty kHz. Other than the rather minimal SC era threshold (169 nJ), GGG demonstrated outstanding general performance characteristics inside the quick-wave infrared With all the best pump pulse Vitality of 464 nJ, which is two occasions reduced than in YAG: the biggest crimson-shifted spectral broadening and the highest spectral Strength density, outperforming KGW and YAG crystals in that component.

], but it would increase way more Price tag to this part. The intra-cavity spectral achieve curve could be modulated by inserting an etalon that reduces the actual obtain in the wavelength with the utmost acquire aspect[

]. Etalon insertion would cause supplemental reduction, having said that, time-to-time optimization would introduce the chance of ingredient injury and instability into the program. A nonlinear regenerative amplifier could specifically supply pulses having a period as low as ninety seven fs as well as a spectral bandwidth of 19 nm[

KGW has a strong Raman spectrum that extends from your ultraviolet into the close to infrared, which makes it practical for An array of applications. The crystal can be employed for a reference product for Raman spectroscopy, in addition to a sample for finding out Raman scattering while in the stable point out.

The scattered photons have a different wavelength and Electrical power in comparison to the incident photons, which generates a Raman spectrum.

Both energies are marked from the dashed traces and their values are labeled from the plots. The equivalent options were also observed here in KGW and YAG crystals, whose spectral broadening dynamics are proven for any comparison in Fig. 4.
