The smart Trick of KYW Crystal That No One is Discussing

The get bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly big in contrast with that of Yb:YAG. This allows for vast wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values perfectly down below 100 fs happen to be reached with passive method locking.

The comparison with Eyeglasses is appropriate Considering that the huge obtain bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.

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 higher effectiveness in laser units.

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW as a result of equivalent dimensions of such chemical features as many as a hundred% of Yb-doping could possibly be reached. This one of a kind characteristic permits ytterbium to go ahead and take area of yttrium with nearly no disruption into the crystal’s lattice.

The monoclinic crystal structures results in a all-natural birefringence, helping to stay away from thermally induced polarization rotation and depolarization reduction.

Raman, luminescence and transmission spectra expose optical functions owing towards the existence of thulium ions, and for that reason the supplies can be even more researched in the scope of laser and luminescence applications.

5 mm in addition to the center of your beam caustic. In an effort to Verify the method matching simulation, we performed the experiment with Ng-Minimize crystal oscillator, which was created Earlier As well as in a identical ailment with simulation [11]. As demonstrated in Determine 3(b) with purple dots and line, the CW output ability is highly depending on the posture of laser crystal as well as the experimental final result coincides nicely with simulation end result. To be a Be aware, multimode operation transpired in experiment in the event the size in the pump beam is much larger than TEM00 cavity method and it results in bigger CW output energy while in the displacement location below 3.5 mm.
