In simple conditions, the Yb:KYW crystal has observed its area of interest in substantial-electrical power laser applications due to its power to crank out substantial Strength ultrashort laser pulses though preserving a compact size. The interaction of its characteristics �?seamless ytterbium substitution, robust absorption traits, ultrashort pulse technology and effectiveness in Power conversion �?positions the Yb:KYW crystal for a cornerstone inside the laser technologies, masking various fields starting from scientific study to industrial apps.
The comparison with glasses is acceptable Considering that the massive get bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heart beat
Color-coded reflectivity of the Bragg mirror as being a functionality of wavelength and angle in the incident beam.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW because of the equivalent dimensions of those chemical aspects approximately 100% of Yb-doping may be obtained. This one of a kind attribute permits ytterbium to take the location of yttrium with almost no disruption for the crystal’s lattice.
The monoclinic crystal buildings results in a pure birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are made use of as lasing resources to produce ultrashort (~ 100-200 fs) high electrical power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser units.
Tungstates are inclined to possess substantial Raman coefficients (�?Raman scattering). Therefore, they're able to crank out major Raman achieve at average optical intensities. It is possible to use the laser crystal itself like a Raman converter.

Higher-power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical programs
Although ytterbium-doped laser obtain media commonly show a little quantum defect, ytterbium-doped tungstates enable for particularly modest values. Such as, a 1030-nm click here Yb:YAG laser would normally be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could possibly be most proficiently pumped all around 981 nm.
This tandem of characteristics has far-achieving implications, especially in the development of compact yet powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at room temperature have been calculated. The emission spectrum and life span from the 3 F four psyched state had been decided. Applying standard and modified Judd–Ofelt theories, the intensity parameters as well as the radiative lifetimes have been calculated and great agreement Together with the experimental benefits was received for both equally theories.
Ask RP Photonics for almost any suggestions about tungstate lasers, like femtosecond lasers and higher-ability lasers.
