In functional phrases, the Yb:KYW crystal has observed its area of interest in significant-ability laser purposes as a result of its capacity to make large Vitality ultrashort laser pulses whilst sustaining a compact size. The interaction of its options �?seamless ytterbium substitution, solid absorption attributes, ultrashort pulse generation and effectiveness in Strength conversion �?positions the Yb:KYW crystal as being a cornerstone in the laser technological know-how, covering assorted fields ranging from scientific exploration to industrial applications.
The comparison with glasses is acceptable For the reason that massive achieve bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the pulse
The absorption and emission spectra of Yb:KYW Crystals Exhibit solid peaks at 980 nm and 1030 nm, respectively, making sure efficient Power conversion and large functionality in laser programs.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW a result of the identical dimensions of such chemical elements as much as 100% of Yb-doping can be obtained. This one of a kind attribute permits ytterbium to take the spot of yttrium with nearly no disruption for the crystal’s lattice.
Adhesion Test Compliant with MIL-C-675C armed forces criteria, an adhesion test involved applying a tape that meets LT-90 specifications on to the lens movie layer. The tape was affixed fully and then eliminated vertically. This treatment was done 3 times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical options owing to the presence of thulium ions, and thus the resources may very well be even further examined during the scope of laser and luminescence purposes.
Spatial structure of your beam as well as corresponding depth profiles I with the output in the laser.
For tungstates, the ytterbium doping focus can be extremely large without the need of considerable quenching as the changed ions have a really very similar ion radius, and the inter-ion length is relatively huge.
By substituting yttrium with ytterbium KYW Crystal from the crystal lattice of Yb:KYW due to comparable sizes of those chemical factors as much as a hundred% of Yb-doping may be accomplished.
The thermal conductivity of common double tungstates is of your get to 3–four W/(K m) �?which isn't terrible in contrast with other laser crystals (Whilst numerous times below for YAG), and fairly massive as opposed With all the thermal conductivity of regular Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is a extraordinary substance that plays an important purpose in laser technological innovation. Its Major functionality is usually to make ultrashort pulses of light, spanning just a couple hundred femtoseconds.
