The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite significant 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 already realized with passive manner locking.

time. Crystals of your compound melts congruently at 1007 oC, having said that soften crystallization of top quality crystal is unachievable because of stage transition at ~920 oC. The very best seeded Remedy process from
FIG. four. Autocorrelation operate of the heart beat 共a兲and spectrum 共b兲of a laser with a rectangular Energetic element for an output electrical power of seven-hundred mW. The width of
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW a result of the identical dimensions of these chemical components around one hundred% of Yb-doping may be realized. This one of a kind attribute permits ytterbium to take the position of yttrium with pretty much no disruption for the crystal’s lattice.
Adhesion Take a look at Compliant with MIL-C-675C military specifications, an adhesion take a look at included implementing a tape that satisfies LT-ninety technical specs on to the lens movie layer. The tape was affixed absolutely and then eliminated vertically. This method was carried out three times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra expose optical options owing into the existence of thulium ions, and therefore the supplies may be even further analyzed from the scope of laser and luminescence purposes.
Spatial composition with the beam as well as corresponding depth profiles I with the output in the laser.
... at half-height had been produced in a master oscillator with selfsynchronization with the axial modes, described inside our earlier short article. 21 The new edition of your laser, as opposed to that explained inside our previously article, utilized an Yb:KYW crystal with an N pcut (optical axis N p in the index ellipsoid was parallel to your propagation direction in the laser radiation), With all the polarization on the created radiation directed along the N m axis.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the identical measurements of such chemical aspects up to one hundred% of Yb-doping might be realized.
Although ytterbium-doped laser obtain media typically exhibit a little quantum defect, ytterbium-doped tungstates allow for for significantly little values. Such as, a 1030-nm Yb:YAG laser would Typically be pumped all over 940 nm, whereas Yb:KGW or Yb:KYW may very well be most efficiently pumped close to 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to get more info its counterpart Yb:KGW, is usually a remarkable product that performs a significant position in laser technological innovation. Its Major perform would be to generate ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Talk to RP Photonics for almost any guidance relating to tungstate lasers, which includes femtosecond lasers and high-electric power lasers.
