The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly substantial in contrast with that of Yb:YAG. This enables for extensive wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values nicely under 100 fs have been attained with passive manner locking.

time. Crystals from the compound melts congruently at 1007 oC, however melt crystallization of top quality crystal is extremely hard as a consequence of section transition at ~920 oC. The highest seeded Remedy method from
The absorption and emission spectra of Yb:KYW Crystals display powerful peaks at 980 nm and 1030 nm, respectively, making certain productive energy conversion and higher efficiency in laser programs.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the equivalent measurements of such chemical factors approximately one hundred% of Yb-doping may very well be obtained. This unique characteristic permits ytterbium to go ahead and take position of yttrium with pretty much no disruption into the crystal’s lattice.
Adhesion Take a look at Compliant with MIL-C-675C military specifications, an adhesion take a look at included implementing a tape that meets LT-90 technical specs on to the lens movie layer. The tape was affixed thoroughly then removed vertically. This technique was performed thrice, leading to no blistering or peeling.

Significant-power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical programs
When ytterbium-doped laser gain media usually exhibit a small quantum defect, ytterbium-doped tungstates allow for specifically smaller values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all-around 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most efficiently pumped close to 981 nm.
This tandem of characteristics has far-reaching implications, particularly in the construction of compact still powerfull lasers.
