The gain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely substantial when compared with that of Yb:YAG. This permits for huge wavelength tunability and for Substantially shorter pulse durations from method-locked lasers. Values well beneath 100 fs have already been accomplished with passive method locking.
In its elemental variety, potassium provides a silvery grey metallic physical appearance, but its compounds (for example potassium hydroxide) are more frequently Employed in industrial and chemical applications.
The datasets used and/or analysed for the duration of The present research out there from the corresponding author on fair request.
That is a preview of membership written content, log in by way of an institution to examine access. Access this informative article
SEMI EL venture is a global provider of components, machines, spare elements and materials for the semiconductor market.
The black line denotes the configuration Along with the crystals positioned in the exact same orientation, though the purple line is underneath the configuration of crystals positioned in orthogonal orientation.
]. This technique was according to The truth that the spectral emission cross-area curves differ from each other when laser polarization is paralleled to the various optical axis of Yb-doped double tungstates[
We created a diode-pumped Yb:KGW regenerative amplifier as being the entrance conclude from the kilohertz terawatt laser technique. Wide bandwidth pulses had been obtained by implementing twin crystals with diverse orientations in their optical axes[
The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The input of the stretcher (incident angle: fifty two°) Which on the compressor incident with the grating have been from your exact same side; as a result, a slight angular tuning of your grating can be designed to get the very best compression result. During the compressor, the enter angle to the grating and the distance concerning the translation phase (S1) along with the transmission grating (TG) had been created to compensate for your stretcher dispersion and all dispersion introduced via the products.
-switched laser output underneath the two crystal placement configurations. The black line denotes the configuration While using the crystals put in a similar orientation, while the red line is under the configuration of crystals put in orthogonal orientation.
Figure four Beam radius variation on the two crystals click here when changing the focal duration from the thermal lensing effect.
Assembling tungsten oxide hydrate nanocrystal colloids formed by laser ablation in liquid into quickly-reaction electrochromic movies.
