Previous operate confirmed that the dual-crystal configuration may be used to compensate to the thermal lensing effect[
While ytterbium-doped laser gain media typically exhibit a small quantum defect, ytterbium-doped tungstates make it possible for for significantly smaller values. For example, a 1030-nm Yb:YAG laser would Generally be pumped all over 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most competently pumped close to 981 nm.
We utilized a transmission grating (TG) for a dispersive component within our stretcher and compressor. A compact configuration was adopted, wherever the stretcher along with the compressor shared one particular grating comparable to that in Ref.
In its elemental kind, potassium has a silvery gray metallic look, but its compounds (which include potassium hydroxide) are more regularly Employed in industrial and chemical apps.
], but it will add considerably more cost to this part. The intra-cavity spectral attain curve could be modulated by inserting an etalon that reduces the actual obtain at the wavelength with the utmost attain aspect[
]. Etalon insertion would result in more loss, on the other hand, time-to-time optimization would introduce the risk of element damage and more info instability for the procedure. A nonlinear regenerative amplifier could straight produce pulses using a period as low as ninety seven fs in addition to a spectral bandwidth of 19 nm[
On the other hand, after Nd3+:YAG turned commercially offered, the interest in CaWO4 dropped sharply. In later a long time, specific other tungstate crystals started to entice a great deal of attention.
Dynamic expression of genes encoding subunits of inward rectifier potassium (Kir) channels during the yellow fever mosquito Aedes aegypti.
]. This method was according to the fact that the spectral emission cross-segment curves vary from one another when laser polarization is paralleled to the several optical axis of Yb-doped double tungstates[
Determine four Beam radius variation on the two crystals although modifying the focal length of the thermal lensing outcome.

-switched laser output underneath the two crystal placement configurations. The black line denotes the configuration Together with the crystals positioned in precisely the same orientation, although the red line is underneath the configuration of crystals put in orthogonal orientation.
This short article has actually been cited by the subsequent publications. This record is produced according to data supplied by Crossref.
