The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is very huge when compared with that of Yb:YAG. This permits for broad wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values perfectly below 100 fs are actually attained with passive method locking.
The comparison with glasses is suitable Considering that the massive gain bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
Femtosecond laser dependant on Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the pulse
The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, ensuring effective Vitality conversion and large functionality in laser devices.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to the comparable measurements of such chemical features up to 100% of Yb-doping might be accomplished. This special characteristic permits ytterbium to go ahead and take place of yttrium with virtually no disruption to the crystal’s lattice.
The monoclinic crystal buildings ends in a normal birefringence, helping to avoid thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra expose optical capabilities owing into the existence of thulium ions, and for that reason the resources may very well be further studied in the scope of laser and luminescence purposes.
Spatial composition of your beam as well as corresponding depth profiles I with the output in the laser.
For tungstates, the ytterbium doping concentration can be quite significant without having substantial quenching since the changed ions have a here very equivalent ion radius, as well as inter-ion length is relatively big.
Superior-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes

Li2WO4-WO3 flux was properly used reducing the growth temperature under 900 oC. As outlined by one crystal x-ray measurements, the crystal corresponds to the P2/n Area group.
