The comparison with glasses is appropriate For the reason that substantial get bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
The Yb:KYW crystal’s proficiency in light absorption at all around 981 nm makes the crystal well suited for diode pumping. It truly is further enhanced by its amazing performance in this method, coupled with its reduced quantum defect.
FIG. 4. Autocorrelation purpose of the heart beat 共a兲and spectrum 共b兲of a laser with a rectangular Lively aspect for an output electrical power of 700 mW. The width of
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW mainly because of the equivalent measurements of such chemical features as much as a hundred% of Yb-doping can be obtained. This unique attribute permits ytterbium to go ahead and take place of yttrium with virtually no disruption to the crystal’s lattice.
The monoclinic crystal buildings leads to a organic birefringence, helping to stay away from thermally induced polarization rotation and depolarization loss.

Spatial composition on the beam as well as the corresponding depth profiles I for the output in the laser.

... Not just the place of crystal in the cavity but additionally the amplification axis of crystal affects the laser Procedure greatly, as the absorption and emission cross sections with the crystal are quite various in accordance with the orientation from the crystal.
The thermal conductivity of widespread double tungstates is from the get to 3–four W/(K m) �?which is not bad when compared with other laser crystals (Though several moments less than for website YAG), and quite big when compared with the thermal conductivity of standard glasses.
Li2WO4-WO3 flux was properly used decreasing the growth temperature under 900 oC. In keeping with single crystal x-ray measurements, the crystal corresponds towards the P2/n Area group.
