Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the pulse

FIG. four. Autocorrelation perform of the heart beat 共a兲and spectrum 共b兲of a laser with a rectangular Lively component for an output ability of 700 mW. The width of

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of related measurements of these chemical components up to a hundred% of Yb-doping may very well be reached. This exclusive characteristic permits ytterbium to go ahead and take spot of yttrium with practically no disruption to the crystal’s lattice.

The monoclinic crystal constructions ends in a pure birefringence, assisting to avoid thermally induced polarization rotation and depolarization decline.

Raman, luminescence and transmission spectra reveal optical characteristics owing towards the presence of thulium ions, and for that reason the products might be more studied here in the scope of laser and luminescence applications.

Spatial framework in the beam as well as the corresponding intensity profiles I at the output of your laser.

... Not simply the posture of crystal in the cavity but also the amplification axis of crystal affects the laser Procedure greatly, as the absorption and emission cross sections of your crystal are pretty distinctive in accordance with the orientation with the crystal.

The thermal conductivity of typical double tungstates is of the buy to 3–four W/(K m) �?which is not lousy when compared with other laser crystals (Even though quite a few moments less than for YAG), and rather big when compared Using the thermal conductivity of usual glasses.

At the same time, a shorter laser wavelength is usually acquired; it is possible to function having a quantum defect well underneath 1%. For a consequence, the heat era can be so smaller that this partly compensates the decrease thermal conductivity.
