The achieve 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 Substantially shorter pulse durations from mode-locked lasers. Values properly underneath one hundred fs are attained with passive method locking.
The comparison with Eyeglasses is suitable Considering that the substantial achieve bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
The Yb:KYW crystal’s proficiency in mild absorption at all around 981 nm helps make the crystal like minded for diode pumping. It is actually additional Increased by its exceptional efficiency in this process, coupled with its small quantum defect.
FIG. 4. Autocorrelation functionality of the heartbeat 共a兲and spectrum 共b兲of a laser with an oblong Lively factor for an output electrical power of 700 mW. The width of
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the equivalent dimensions of such chemical features up to 100% of Yb-doping might be achieved. This special attribute permits ytterbium to go ahead and take location of yttrium with nearly no disruption on the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C navy benchmarks, an adhesion test involved applying a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed completely and afterwards taken off vertically. This course of action was performed thrice, resulting in no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and therefore are utilized as lasing materials to deliver ultrashort (~ one hundred-200 fs) substantial electrical power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact get more info laser systems.
Tungstates are likely to possess large Raman coefficients (�?Raman scattering). For that reason, they might crank out important Raman attain at reasonable optical intensities. It is possible to use the laser crystal alone to be a Raman converter.
... at 50 percent-peak were produced within a learn oscillator with selfsynchronization on the axial modes, described within our earlier report. 21 The new version on the laser, in contrast to that explained inside our earlier short article, utilized an Yb:KYW crystal using an N pcut (optical axis N p in the index ellipsoid was parallel into the propagation path with the laser radiation), Using the polarization on the created radiation directed together the N m axis.
Substantial-ability repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical applications
