The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is very significant in comparison with that of Yb:YAG. This allows for large wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values very well beneath a hundred fs have already been obtained with passive mode locking.
This can be a preview of membership material, log in by using an institution to examine access. Accessibility this informative article
We current a dual-crystal Yb:KGW laserthat iscapable to work as being a Q-switched oscillator with output ability as much as 24 W and pulse length of 20 ns,or like a regenerative amplifier with output electric power as many as 21 W and pulse duration below two hundred fs immediately after compression of chirped pulses. Both equally lasers have exceptional beam good quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Display screen powerful peaks at 980 nm and 1030 nm, respectively, making certain productive Vitality conversion and substantial general performance in laser units.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to the equivalent measurements of those chemical things nearly a hundred% of Yb-doping could be obtained. This distinctive characteristic permits ytterbium to take the location of yttrium with nearly no disruption for the crystal’s lattice.
The monoclinic crystal buildings brings about a purely natural birefringence, assisting to prevent thermally induced polarization rotation click here and depolarization reduction.
Raman, luminescence and transmission spectra expose optical features owing for the presence of thulium ions, and thus the components may be even further examined during the scope of laser and luminescence purposes.
Spatial framework on the beam as well as the corresponding intensity profiles I on the output on the laser.
For tungstates, the ytterbium doping focus can be very superior without the need of important quenching because the changed ions have an incredibly similar ion radius, as well as the inter-ion length is fairly large.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the very similar measurements of these chemical components up to one hundred% of Yb-doping could possibly be accomplished.

Li2WO4-WO3 flux was properly applied lowering The expansion temperature underneath 900 oC. Based on solitary crystal x-ray measurements, the crystal corresponds on the P2/n House team.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at home temperature were measured. The emission spectrum and life time with the three File four thrilled state have been decided. Applying standard and modified Judd–Ofelt theories, the intensity parameters and also the radiative lifetimes had been calculated and very good arrangement Together with the experimental effects was received for both equally theories.
Right here you could submit issues and feedback. So far as they get recognized through the writer, they can seem earlier mentioned this paragraph along with the creator’s solution. The writer will make a decision on acceptance dependant on particular requirements. In essence, The problem need to be of adequately wide curiosity.
