In practical terms, the Yb:KYW crystal has identified its area of interest in superior-electrical power laser programs on account of its capacity to create large Power ultrashort laser pulses while maintaining a compact sizing. The interaction of its functions �?seamless ytterbium substitution, solid absorption features, ultrashort pulse era and efficiency in Power conversion �?positions the Yb:KYW crystal as a cornerstone during the laser technological know-how, masking various fields ranging from scientific research to industrial applications.
The comparison with Eyeglasses is suitable Considering that the significant attain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
time. Crystals on the compound melts congruently at 1007 oC, even so melt crystallization of top quality crystal is extremely hard as a result of phase transition at ~920 oC. The best seeded Resolution approach from
The absorption and emission spectra of Yb:KYW Crystals Display screen powerful peaks at 980 nm and 1030 nm, respectively, making certain successful energy conversion and large effectiveness in laser units.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW a result of the identical measurements of those chemical things up to 100% of Yb-doping may very well be accomplished. This exclusive attribute permits ytterbium to go ahead and take spot of yttrium with nearly no disruption for the crystal’s lattice.
The monoclinic crystal constructions ends in a normal birefringence, assisting to keep away from thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra reveal optical characteristics owing into the existence of thulium ions, and thus the resources may very well be further studied during the scope of laser click here and luminescence applications.
five mm in addition to the middle in the beam caustic. As a way to Verify the manner matching simulation, we done the experiment with Ng-Lower crystal oscillator, which was created Beforehand As well as in a exact same condition with simulation [eleven]. As proven in Determine three(b) with crimson dots and line, the CW output energy is very dependent on the posture of laser crystal along with the experimental result coincides very well with simulation outcome. For a Be aware, multimode operation happened in experiment when the measurement of your pump beam is greater than TEM00 cavity method and it results in increased CW output ability in the displacement region below three.five mm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is usually a remarkable material that performs a significant purpose in laser technological know-how. Its Most important purpose will be to make ultrashort pulses of light, spanning just some hundred femtoseconds.
Inquire RP Photonics for virtually any suggestions concerning tungstate lasers, which include femtosecond lasers and higher-ability lasers.
