Prior perform confirmed that the twin-crystal configuration may be used to compensate to the thermal lensing impact[

While ytterbium-doped laser acquire media typically exhibit a small quantum defect, ytterbium-doped tungstates let for specially compact values. For example, a 1030-nm Yb:YAG laser would Ordinarily be pumped close to 940 nm, While Yb:KGW or Yb:KYW may be most effectively pumped close to 981 nm.

A not-for-gain Business, IEEE is the world's major specialized Expert organization dedicated to advancing know-how for the advantage of humanity.

Along with its use as a Raman crystal, KGW is also Utilized in other optical applications, for example in laser systems and being a scintillator in healthcare imaging.

Substitute in the Personal computer for a better 1 or maybe a fine adjustment from the Laptop orientation along with the used high voltage is needed to stay away from this phenomenon. A fast pulse picker can be employed to improve the nanosecond-scale distinction of your output main pulse.

The black line denotes the configuration Together with the crystals put in the same orientation, even though the red line is underneath the configuration of crystals placed in orthogonal orientation.

]. This process was depending on The truth that the spectral emission cross-segment curves vary from each other when laser polarization is paralleled to different optical axis of Yb-doped double tungstates[

You should settle for terms of use.   Please tick the box to substantiate you concur that the title, comment and conflicts of desire (if accepted) are going to be obvious on the website plus your comment might be printed during the journal with the Editor’s discretion. *

Tungstates have a tendency to have significant Raman coefficients (�?Raman scattering). Hence, they are able to produce sizeable Raman gain at moderate optical intensities. It is possible to use the laser crystal by itself as a Raman converter.

Both equally energies are more info marked via the dashed traces and their values are labeled inside the plots. The equivalent options have been also observed in KGW and YAG crystals, whose spectral broadening dynamics are revealed for just a comparison in Fig. four.
