Working with our promoting offer, it is possible to Display screen your logo, even more down below your item description, and these will been witnessed by lots of photonics pros.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a outstanding materials that plays a crucial position in laser know-how. Its Key purpose will be to crank out ultrashort pulses of light, spanning only a few hundred femtoseconds.
time. Crystals of the compound melts congruently at 1007 oC, however soften crystallization of high quality crystal is impossible as a consequence of stage changeover at ~920 oC. The best seeded Resolution technique from
The absorption and emission spectra of Yb:KYW Crystals Exhibit solid peaks at 980 nm and 1030 nm, respectively, making sure economical energy conversion and high effectiveness in laser devices.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the related measurements of such chemical features nearly a hundred% of Yb-doping could be accomplished. This distinctive characteristic permits ytterbium to go ahead and take place of yttrium with practically no disruption towards the crystal’s lattice.
Adhesion Examination Compliant with MIL-C-675C armed forces requirements, an adhesion examination concerned making use of a tape that fulfills LT-ninety technical specs on to the lens movie layer. The tape was affixed thoroughly and then eliminated vertically. This method was carried out three times, resulting in no blistering or peeling.

Spatial framework with the beam plus the corresponding depth profiles I with the output on the laser.

... Not just the place of crystal inside the cavity but in addition the amplification axis of crystal impacts the laser operation significantly, because the absorption and emission cross sections from the crystal are really distinct according to the orientation of the crystal.
The thermal conductivity of typical double tungstates is of your purchase to three–4 W/(K m) �?which isn't bad when compared with other laser crystals (Though quite a few moments below for YAG), and rather big when compared While using the thermal conductivity of typical glasses.
