The get bandwidth e.g. of Yb:KGW and Yb:KYW is very big in contrast with that of Yb:YAG. This allows for broad wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values nicely below a hundred fs are actually reached with passive manner locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a impressive material that plays an important job in laser technologies. Its Main operate would be to produce ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light absorption at close to 981 nm would make the crystal well matched for diode pumping. It is additional enhanced by its outstanding efficiency in this process, coupled with its low quantum defect.
Colour-coded reflectivity of a Bragg mirror for a functionality of wavelength and angle with the incident beam.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW a result of the very similar dimensions of such chemical components approximately one hundred% of Yb-doping may very well be obtained. This unique characteristic permits ytterbium to go ahead and take put of yttrium with virtually no disruption to the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C armed service requirements, an adhesion take a look at concerned applying a tape that meets LT-90 specs on to the lens movie layer. The tape was affixed fully after which taken out vertically. This technique was done 3 times, leading to no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical features owing into the existence of thulium ions, and thus the supplies may be more analyzed during the scope of laser and luminescence purposes.

For tungstates, the ytterbium doping concentration can be quite high with no significant quenching since the changed ions have a very related ion radius, and the inter-ion distance is comparatively massive.
Even so, once Nd3+:YAG grew to become commercially offered, the fascination in CaWO4 dropped sharply. In afterwards decades, specific other tungstate crystals began to catch the attention of lots of consideration.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison click here to its counterpart Yb:KGW, is actually a impressive content that plays a vital part in laser know-how. Its Key operate is always to generate ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
