The get bandwidth e.g. of Yb:KGW and Yb:KYW may be very substantial when compared with that of Yb:YAG. This enables for vast wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values effectively beneath 100 fs have been achieved with passive manner locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a amazing material that performs an essential job in laser technologies. Its Major purpose is to produce ultrashort pulses of light, spanning just a couple hundred femtoseconds.
time. Crystals in the compound melts congruently at 1007 oC, nevertheless soften crystallization of top quality crystal is impossible as a result of section changeover at ~920 oC. The very best seeded Answer system from
FIG. 4. Autocorrelation functionality of the heart beat 共a兲and spectrum 共b兲of a laser with an oblong active ingredient for an output energy of seven hundred mW. The width of
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW as a result of very similar sizes of these chemical aspects nearly one hundred% of Yb-doping could possibly be achieved. This exclusive attribute permits ytterbium to take the location of yttrium with nearly no disruption towards the crystal’s lattice.
The monoclinic crystal buildings results in a organic birefringence, assisting to steer clear of thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical capabilities owing towards the presence of thulium ions, and for that reason the supplies could be even more analyzed within the scope of laser and luminescence purposes.
Tungstates are inclined to obtain high Raman coefficients (�?Raman scattering). Therefore, they're able to crank out major Raman get at moderate optical intensities. It is achievable to make use of the laser crystal alone for a Raman converter.
... at half-height ended up generated inside of a grasp oscillator with selfsynchronization of your axial modes, described in our earlier posting. 21 The new edition in the laser, unlike that explained in our previously post, made use of an Yb:KYW crystal with the N pcut (optical axis N p in the index ellipsoid was parallel to the propagation path on the laser radiation), Along with the polarization with the produced radiation directed together the N m axis.
Even so, as soon as Nd3+:YAG turned commercially offered, the fascination in CaWO4 dropped sharply. In later website many years, specific other tungstate crystals started to catch the attention of plenty of interest.
