The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is very massive compared with that of Yb:YAG. This allows for broad wavelength tunability and for A great deal shorter pulse durations from method-locked lasers. Values nicely under a hundred fs have been accomplished with passive manner locking.

The Yb:KYW crystal’s proficiency in mild absorption at around 981 nm would make the crystal well matched for diode pumping. It truly is additional Increased by its remarkable efficiency in this method, coupled with its small quantum defect.

FIG. 4. Autocorrelation purpose of the heartbeat 共a兲and spectrum 共b兲of the laser with a rectangular Energetic element for an output energy of seven hundred mW. The width of

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of comparable dimensions of those chemical features nearly 100% of Yb-doping could be realized. This one of a kind characteristic permits ytterbium to go ahead and take location of yttrium with just about no disruption to your crystal’s lattice.

The monoclinic crystal constructions leads to a organic birefringence, assisting to keep away from thermally induced polarization rotation and depolarization reduction.

Spatial framework with the beam and also the corresponding intensity profiles I with the output from the laser.

For tungstates, the ytterbium doping focus can be quite superior without substantial quenching because the website changed ions have a very equivalent ion radius, and the inter-ion length is relatively huge.

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW mainly because of the related measurements of those chemical things approximately one hundred% of Yb-doping could possibly be reached.
