In realistic conditions, the Yb:KYW crystal has observed its market in superior-electric power laser applications as a result of its ability to produce higher Strength ultrashort laser pulses although preserving a compact dimensions. The interaction of its functions �?seamless ytterbium substitution, strong absorption attributes, ultrashort pulse generation and effectiveness in Electricity conversion �?positions the Yb:KYW crystal as a cornerstone from the laser technological know-how, covering varied fields ranging from scientific research to industrial purposes.
The comparison with glasses is suitable Because the substantial attain bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
The Yb:KYW crystal’s proficiency in light absorption at all over 981 nm can make the crystal well suited for diode pumping. It can be even further Increased by its exceptional effectiveness in this process, coupled with its very low quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Screen powerful peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Power conversion and large general performance in laser systems.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to related sizes of such chemical aspects nearly one hundred% of Yb-doping may very well be reached. This special attribute permits ytterbium to take the location of yttrium with pretty much no disruption to your crystal’s lattice.
Following air drying and subsequent cleansing with a cotton cloth soaked in alcohol, the movie surface area showed no indications of peeling or scratches.
FIG. one. Optical structure of the laser with immediate pumping While using the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output
Spatial composition of the beam as well as the corresponding depth profiles I for the output of the laser.
For tungstates, the ytterbium doping focus can be extremely high without substantial quenching because the replaced ions have an incredibly comparable ion radius, as well as the inter-ion distance is fairly significant.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to the related dimensions of these chemical aspects approximately one hundred% of Yb-doping can be realized.
Even though website ytterbium-doped laser acquire media commonly exhibit a little quantum defect, ytterbium-doped tungstates enable for particularly modest values. One example is, a 1030-nm Yb:YAG laser would Typically be pumped all-around 940 nm, whereas Yb:KGW or Yb:KYW may very well be most efficiently pumped all around 981 nm.
