The gain bandwidth e.g. of Yb:KGW and Yb:KYW is rather big in comparison with that of Yb:YAG. This enables for extensive wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values effectively beneath one hundred fs are obtained with passive manner locking.
That is a preview of subscription information, log in through an establishment to check obtain. Accessibility this article
time. Crystals on the compound melts congruently at 1007 oC, even so melt crystallization of high quality crystal is impossible due to period transition at ~920 oC. The highest seeded Remedy strategy from
The absorption and emission spectra of Yb:KYW Crystals Display screen powerful peaks at 980 nm and 1030 nm, respectively, making certain successful Electrical power conversion and higher overall performance in laser methods.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the related measurements of those chemical features up to a hundred% of Yb-doping may very well be obtained. This unique attribute permits ytterbium to go ahead and take position of yttrium with just about no disruption to your crystal’s lattice.
The monoclinic crystal constructions leads to a organic birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are utilised as lasing components to produce ultrashort (~ 100-two hundred fs) large energy pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser techniques.
A superior brightnessQ-switched oscillator and KYW Crystal regenerative amplifier determined by a dual-crystal Yb:KGW laser
For tungstates, the ytterbium doping concentration can be extremely higher devoid of substantial quenching since the changed ions have a very related ion radius, plus the inter-ion length is relatively huge.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW due to the identical sizes of such chemical aspects up to a hundred% of Yb-doping could possibly be accomplished.
On account of previously detected destructive conduct which originated in the community you are using, remember to request unblock to website.
This tandem of characteristics has much-achieving implications, particularly in the construction of compact nonetheless powerfull lasers.
