In simple conditions, the Yb:KYW crystal has located its area of interest in substantial-electric power laser apps resulting from its power to crank out substantial Strength ultrashort laser pulses although preserving a compact size. The interaction of its characteristics �?seamless ytterbium substitution, robust absorption traits, ultrashort pulse technology and efficiency in Electrical power conversion �?positions the Yb:KYW crystal to be a cornerstone inside the laser technological innovation, masking numerous fields ranging from scientific exploration to industrial applications.

time. Crystals on the compound melts congruently at 1007 oC, even so melt crystallization of high quality crystal is difficult on account of section transition at ~920 oC. The highest seeded solution technique from
The absorption and emission spectra of Yb:KYW Crystals display powerful peaks at 980 nm and 1030 nm, respectively, making certain successful energy conversion and higher functionality in laser programs.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of identical sizes of these chemical components around one hundred% of Yb-doping may very well be obtained. This unique attribute permits ytterbium to take the area of yttrium with just about no disruption to your crystal’s lattice.
Adhesion Test Compliant with MIL-C-675C navy benchmarks, an adhesion test involved applying a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed entirely and afterwards eradicated vertically. This procedure was executed thrice, leading to no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are employed as lasing components to produce ultrashort (~ a hundred-two hundred fs) large energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser methods.
five mm in addition to the middle on the beam caustic. In an effort to Examine the mode matching simulation, we carried out the experiment with Ng-Reduce crystal oscillator, which was developed Beforehand As well as in a identical condition with simulation [eleven]. As shown in Determine 3(b) with pink dots and line, the CW output electricity is highly dependent on the place of laser crystal and the experimental consequence coincides nicely with simulation consequence. As being a Notice, multimode Procedure occurred in experiment if the size on the pump beam is larger than TEM00 cavity mode and it will cause higher CW output electrical power from the displacement location below 3.five mm.
For tungstates, the ytterbium doping focus can be very significant with out major quenching because the replaced ions have an exceptionally similar ion radius, along with the inter-ion length is pretty big.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the very similar sizes of such chemical factors up to 100% of Yb-doping can be reached.
Though ytterbium-doped laser gain media usually show a small quantum defect, ytterbium-doped tungstates let for specially compact values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped around 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most successfully pumped all around 981 nm.
Li2WO4-WO3 flux was productively used decreasing the growth temperature underneath 900 oC. According to single crystal x-ray measurements, the crystal corresponds into the P2/n House team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is really a outstanding material that performs a crucial purpose in laser know-how. Its click here Principal operate would be to generate ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Simultaneously, a shorter laser wavelength could be attained; it is achievable to operate which has a quantum defect properly beneath one%. As being a consequence, the warmth generation is often so small this partly compensates the reduce thermal conductivity.
