The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is rather large in comparison with that of Yb:YAG. This enables for large wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values properly down below a hundred fs happen to be attained with passive method locking.
This unique characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at reduced overall publicity, and drives apps like deep-tissue multiphoton microscopy and superior-precision eye operation
The Yb:KYW crystal’s proficiency in mild absorption at about 981 nm would make the crystal well matched for diode pumping. It's more Improved by its amazing performance in this method, coupled with its small quantum defect.
FIG. 4. Autocorrelation purpose of the pulse 共a兲and spectrum 共b兲of a laser with an oblong Energetic element for an output power of seven hundred mW. The width of
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of very similar dimensions of these chemical aspects as many as a hundred% of Yb-doping can be attained. This exclusive characteristic permits ytterbium to take the place of yttrium with practically no disruption to the crystal’s lattice.
The monoclinic crystal constructions leads to a all-natural birefringence, assisting to stay clear of thermally get more info induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical features owing towards the presence of thulium ions, and as a consequence the materials might be more studied inside the scope of laser and luminescence programs.
Spatial composition of your beam as well as corresponding depth profiles I on the output in the laser.
For tungstates, the ytterbium doping focus can be very substantial without considerable quenching since the changed ions have an exceptionally similar ion radius, along with the inter-ion length is relatively huge.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW mainly because of the identical measurements of these chemical things approximately 100% of Yb-doping can be realized.
On account of Formerly detected destructive habits which originated in the community you are utilizing, be sure to request unblock to web page.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is actually a exceptional materials that performs a very important purpose in laser know-how. Its Key operate will be to make ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Inquire RP Photonics for virtually any suggestions concerning tungstate lasers, like femtosecond lasers and high-electric power lasers.
