In functional phrases, the Yb:KYW crystal has located its area of interest in substantial-electric power laser purposes as a consequence of its power to crank out large Power ultrashort laser pulses even though keeping a compact dimension. The interaction of its capabilities �?seamless ytterbium substitution, sturdy absorption qualities, ultrashort pulse technology and effectiveness in energy conversion �?positions the Yb:KYW crystal as a cornerstone from the laser technological innovation, masking varied fields ranging from scientific investigate to industrial programs.

We present a twin-crystal Yb:KGW laserthat iscapable to work to be a Q-switched oscillator with output energy as many as 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output electricity approximately 21 W and pulse length beneath two hundred fs after compression of chirped pulses. Both lasers have exceptional beam excellent with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Show robust peaks at 980 nm and 1030 nm, respectively, guaranteeing effective Vitality conversion and substantial effectiveness in laser devices.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of very similar dimensions of those chemical things nearly a hundred% of Yb-doping could be accomplished. This distinctive characteristic permits ytterbium to go ahead and take position of yttrium with just about no disruption to your crystal’s lattice.
The monoclinic crystal constructions results in a natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical capabilities owing to the existence of thulium ions, and as a consequence the elements may be further more analyzed from the scope of laser and luminescence applications.
Spatial composition of your beam as well as corresponding depth profiles I on the output in the laser.
For tungstates, the ytterbium doping concentration can be extremely substantial without significant quenching as the replaced ions have an incredibly identical ion radius, and also the inter-ion distance is fairly large.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW as a result of comparable sizes of such chemical things approximately 100% of Yb-doping might be obtained.
Whilst ytterbium-doped laser acquire media typically exhibit a small quantum defect, ytterbium-doped tungstates enable for notably modest values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all-around 940 nm, Whilst Yb:KGW or Yb:KYW may be most proficiently pumped close to 981 nm.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at space temperature ended up calculated. The emission spectrum and life span from the 3 F 4 enthusiastic point out were being identified. Utilizing normal and modified Judd–Ofelt theories, the intensity parameters as well as radiative lifetimes had been calculated and very good arrangement Together with the experimental effects was received for equally theories.
