The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is very substantial as opposed with that of Yb:YAG. This allows for vast wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values very well below 100 fs are obtained with passive manner locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is often a remarkable product that performs a crucial function in laser technologies. Its Most important purpose is to make ultrashort pulses of light, spanning just some hundred femtoseconds.
Femtosecond laser based upon Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the heart beat
FIG. 4. Autocorrelation operate of the pulse 共a兲and spectrum 共b兲of a laser with an oblong Energetic ingredient for an output electrical power of seven-hundred mW. The width of
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW mainly because of the very similar measurements of these chemical things around 100% of Yb-doping can be reached. This distinctive attribute permits ytterbium to take the place of yttrium with just about no disruption for the crystal’s lattice.
The monoclinic crystal constructions leads to a purely natural birefringence, assisting to steer clear of thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical characteristics owing for the existence of thulium ions, and for that reason the components could be even further studied from the scope of laser and luminescence programs.
Spatial framework of the beam and the corresponding depth profiles I for the output of the laser.
For tungstates, the ytterbium doping focus can be very significant devoid of important quenching as the replaced ions have an incredibly comparable ion radius, as well as inter-ion length is fairly significant.
... Don't just the position of crystal within the cavity but in addition the amplification axis of crystal impacts the laser operation greatly, because the absorption and emission cross sections on the crystal are quite various in accordance with the orientation in the crystal.
Because of Beforehand detected malicious habits which originated from the network you might be employing, please request unblock to web page.
This tandem of attributes has much-reaching implications, notably in the development of compact nonetheless powerfull lasers.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is often a exceptional product that performs a significant part in laser technology. click here Its Key perform should be to create ultrashort pulses of light, spanning just a few hundred femtoseconds.
