The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is actually a impressive substance that performs a very important role in laser engineering. Its Principal operate is usually to create ultrashort pulses of light, spanning just some hundred femtoseconds.
time. Crystals of your compound melts congruently at 1007 oC, on the other hand melt crystallization of top quality crystal is impossible resulting from phase transition at ~920 oC. The top seeded Option technique from
The absorption and emission spectra of Yb:KYW Crystals Exhibit strong peaks at 980 nm and 1030 nm, respectively, making certain productive Electricity conversion and high effectiveness in laser units.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW a result of the very similar sizes of these chemical features as much as 100% of Yb-doping could possibly be reached. This exceptional attribute permits ytterbium to take the location of yttrium with nearly no disruption for the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C armed service requirements, an adhesion examination concerned implementing a tape that satisfies LT-90 specs onto the lens movie layer. The tape was affixed absolutely and check here after that taken out vertically. This treatment was executed thrice, causing no blistering or peeling.

Spatial framework from the beam and also the corresponding depth profiles I in the output of your laser.
... at half-top ended up generated inside of a grasp oscillator with selfsynchronization of the axial modes, described inside our earlier posting. 21 The new version from the laser, unlike that described inside our before write-up, made use of an Yb:KYW crystal using an N pcut (optical axis N p with the index ellipsoid was parallel towards the propagation course of your laser radiation), with the polarization in the created radiation directed together the N m axis.
... Not just the place of crystal inside the cavity but in addition the amplification axis of crystal impacts the laser operation greatly, as the absorption and emission cross sections on the crystal are very diverse according to the orientation of the crystal.
