The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, can be a amazing product that performs a very important role in laser technologies. Its Main operate will be to deliver ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the heartbeat
FIG. four. Autocorrelation purpose of the heart beat 共a兲and spectrum 共b兲of the laser with a rectangular Lively element for an output electricity of seven-hundred mW. The width of
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW a result of the very similar dimensions of such chemical aspects nearly 100% of Yb-doping might be reached. This one of a kind attribute permits ytterbium to go ahead and take place of yttrium with practically no disruption to your crystal’s lattice.
The monoclinic crystal structures results in a natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra expose optical options owing to the presence of thulium ions, and so the elements can be further more examined during the scope of laser and luminescence purposes.
Spatial structure in the beam as well as the corresponding intensity profiles I in the output from the laser.

... Don't just the posture of crystal in the cavity but also the amplification axis of crystal affects the laser Procedure enormously, as the absorption and emission cross sections with the crystal are rather distinctive according to the orientation of your crystal.

At the same time, a shorter laser wavelength is often acquired; it is possible to function having a quantum defect perfectly beneath one%. Like a consequence, the warmth era is usually so modest that this partly compensates the decrease thermal conductivity.
