The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, can be a amazing product that performs a significant job in laser technologies. Its Main perform is always to create ultrashort pulses of light, spanning just some hundred femtoseconds.
Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the heartbeat
FIG. four. Autocorrelation function of the pulse 共a兲and spectrum 共b兲of a laser with a rectangular Lively factor for an output electricity of seven hundred mW. The width of
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW because of the equivalent measurements of those chemical factors around one hundred% of Yb-doping may very well be achieved. This distinctive characteristic permits ytterbium to take the location of yttrium with nearly no disruption into the crystal’s lattice.
The monoclinic crystal structures results in a natural birefringence, assisting to stay clear of thermally induced polarization rotation and depolarization decline.

Spatial construction in the beam as well as the corresponding intensity profiles I within the output of your laser.
For tungstates, the ytterbium doping focus can be very significant devoid of important quenching because the replaced ions have an extremely equivalent ion radius, along with the website inter-ion length is comparatively huge.
... Not just the place of crystal within the cavity but also the amplification axis of crystal has an effect on the laser Procedure tremendously, because the absorption and emission cross sections with the crystal are very distinct according to the orientation with the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is actually a exceptional content that plays an essential role in laser technologies. Its primary functionality will be to produce ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
