In useful phrases, the Yb:KYW crystal has uncovered its area of interest in substantial-ability laser applications because of its capability to produce large Electrical power ultrashort laser pulses although protecting a compact size. The interaction of its options �?seamless ytterbium substitution, sturdy absorption attributes, ultrashort pulse era and performance in Strength conversion �?positions the Yb:KYW crystal as being a cornerstone inside the laser technology, masking numerous fields ranging from scientific investigation to industrial purposes.
This exclusive attribute of ultrafast pulses enables nonlinear optical interaction with tissue at very low Total exposure, and drives purposes like deep-tissue multiphoton microscopy and substantial-precision eye surgical procedures
The Yb:KYW crystal’s proficiency in gentle absorption at all over 981 nm can make the crystal like minded for diode pumping. It is actually more Improved by its remarkable efficiency in this method, coupled with its small quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Display screen powerful peaks at 980 nm and 1030 nm, respectively, ensuring productive Strength conversion and significant general performance in laser systems.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW a result of the very similar dimensions of such chemical elements as much as 100% of Yb-doping could be attained. This exceptional attribute permits ytterbium to take the spot of yttrium with almost no disruption to your crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C military benchmarks, an adhesion examination included implementing a tape that fulfills LT-90 technical specs on to the lens movie layer. The tape was affixed absolutely and afterwards taken off vertically. This method was executed 3 times, causing no blistering or peeling.
Raman, luminescence and transmission spectra expose optical capabilities owing for the existence of thulium ions, and as a consequence the supplies could possibly be even more researched in the scope of laser and luminescence programs.
Spatial construction in the beam as well as the corresponding intensity profiles I within the output from the laser.
EKSMA Optics employs cookies to supply you with the finest browsing encounter. If you go on to use our services, We are going to suppose that you comply with using this sort of cookies.
... Not merely the situation of crystal during the cavity but also the amplification axis of crystal affects the laser operation significantly, because the absorption and emission cross sections in the crystal are very unique based on the here orientation on the crystal.
While ytterbium-doped laser acquire media commonly show a little quantum defect, ytterbium-doped tungstates make it possible for for significantly small values. For instance, a 1030-nm Yb:YAG laser would Ordinarily be pumped around 940 nm, Whilst Yb:KGW or Yb:KYW could be most efficiently pumped all-around 981 nm.
This tandem of characteristics has far-achieving implications, specially in the development of compact but powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature ended up calculated. The emission spectrum and life span from the 3 F 4 enthusiastic condition were being identified. Utilizing typical and modified Judd–Ofelt theories, the depth parameters along with the radiative lifetimes have been calculated and great settlement Along with the experimental benefits was received for each theories.
Inquire RP Photonics for just about any suggestions concerning tungstate lasers, which includes femtosecond lasers and significant-electrical power lasers.
