The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial in comparison with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values well beneath 100 fs have been accomplished with passive mode locking.

Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in the regenerative amplifier by spectral profiling of the heartbeat
The absorption and emission spectra of Yb:KYW Crystals Show robust peaks at 980 nm and 1030 nm, respectively, guaranteeing successful Electricity conversion and superior performance in laser methods.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW a result of the very similar dimensions of such chemical features up to 100% of Yb-doping might be attained. This special characteristic permits ytterbium to take the location of yttrium with nearly no disruption on the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C navy benchmarks, an adhesion test involved applying a tape that meets LT-ninety technical specs on to the lens film layer. The tape was affixed entirely and afterwards taken off vertically. This course of action was executed 3 times, leading to no blistering or peeling.

Spatial framework in the beam and the corresponding intensity profiles I for the output with the laser.
For tungstates, the ytterbium doping concentration can be quite significant with out major quenching as the replaced ions have an incredibly identical ion radius, and also the inter-ion distance is fairly substantial.
... Not only the place of crystal inside the cavity but in addition the amplification axis of crystal impacts the laser operation significantly, because the absorption and emission cross sections of your crystal are pretty distinctive in accordance with the orientation on the crystal.
Although ytterbium-doped laser achieve media commonly show a small quantum defect, ytterbium-doped tungstates let for specially smaller values. One example is, a 1030-nm Yb:YAG laser would Commonly be pumped all over 940 nm, While Yb:KGW or Yb:KYW could possibly be most effectively pumped about 981 nm.
