In sensible phrases, the Yb:KYW crystal has discovered its market in higher-energy laser purposes on account of its capacity to crank out higher Electrical power ultrashort laser pulses though maintaining a compact dimension. The interaction of its characteristics �?seamless ytterbium substitution, solid absorption features, ultrashort pulse generation and performance in energy conversion �?positions the Yb:KYW crystal as a cornerstone while in the laser technological know-how, masking assorted fields ranging from scientific research to industrial applications.
The comparison with Eyeglasses is appropriate since the huge gain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We current a dual-crystal Yb:KGW laserthat iscapable to work like a Q-switched oscillator with output power up to 24 W and pulse duration of 20 ns,or as a regenerative amplifier with output ability around 21 W and pulse period below two hundred fs after compression of chirped pulses. Both equally lasers have excellent beam high quality with beam parameter M2
Colour-coded reflectivity of the Bragg mirror as a operate of wavelength and angle of your incident beam.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to the related sizes of such chemical features as much as 100% of Yb-doping might be accomplished. This exceptional attribute permits ytterbium to go ahead and take put of yttrium with nearly no disruption to your crystal’s lattice.
Just before the event of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser get medium. It was in actual fact used in the 1st constantly running crystal laser.

... Not just the placement of crystal from the cavity but in addition the amplification axis of crystal influences the laser operation drastically, since the absorption and emission cross sections in the crystal are really various based on the orientation in the crystal.
Even though ytterbium-doped laser achieve media frequently exhibit a small quantum defect, ytterbium-doped tungstates enable for especially tiny values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped around 940 nm, whereas Yb:KGW or Yb:KYW may be most successfully pumped all-around 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is actually a outstanding substance that plays a very important part in laser technologies. Its Most important purpose should be to create ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
