In simple conditions, the Yb:KYW crystal has uncovered its specialized niche in superior-energy laser programs resulting from its capacity to make substantial energy ultrashort laser pulses while protecting a compact dimensions. The interplay of its attributes �?seamless ytterbium substitution, potent absorption features, ultrashort pulse generation and effectiveness in energy conversion �?positions the Yb:KYW crystal like a cornerstone in the laser technological know-how, covering varied fields ranging from scientific investigate to industrial programs.

The comparison with glasses is suitable Because the large get bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.

time. Crystals on the compound melts congruently at 1007 oC, nonetheless melt crystallization of top quality crystal is unattainable as a result of stage changeover at ~920 oC. The very best seeded solution strategy from

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW a result of the identical dimensions of those chemical aspects nearly a hundred% of Yb-doping can be achieved. This distinctive characteristic permits ytterbium to go ahead and take place of yttrium with almost no disruption to the crystal’s lattice.

Immediately after air drying and subsequent cleaning that has a cotton cloth soaked in Liquor, the movie surface showed no signs of peeling or scratches.

Raman, luminescence and transmission spectra expose optical characteristics owing on the presence of thulium ions, and therefore the resources might be additional researched inside the scope of laser and luminescence purposes.

Spatial framework on the beam along with the corresponding intensity profiles I in the output of the laser.

For tungstates, the ytterbium doping concentration can be extremely higher devoid of substantial quenching since the changed ions have a very equivalent ion radius, as well as inter-ion length is relatively huge.

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to related sizes of such chemical aspects around a hundred% of Yb-doping may very well be attained.
