The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large in contrast with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values very well down below a hundred fs happen to be attained with passive method locking.
This exceptional attribute of ultrafast pulses allows nonlinear optical conversation with tissue at lower All round publicity, and drives programs such as deep-tissue multiphoton microscopy and significant-precision eye operation
time. Crystals in the compound melts congruently at 1007 oC, nevertheless melt crystallization of high quality crystal is difficult on account of section transition at ~920 oC. The best seeded Answer strategy from

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by powerful linear arrays of semiconductor injection lasers owning fiber output. To circumvent spectral narrowing through amplification along with the corresponding lengthening from the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals have been utilized, While using the spectral maxima on the amplification shifted relative to each other and with spectral profiling on the amplified radiation.
Ahead of the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser get medium. It absolutely was in reality Utilized in the first constantly running crystal laser.

Tungstates are likely to have large Raman coefficients (�?Raman scattering). For that reason, they can produce click here considerable Raman obtain at moderate optical intensities. It is feasible to use the laser crystal alone to be a Raman converter.
For tungstates, the ytterbium doping focus can be very superior without having major quenching since the replaced ions have an incredibly similar ion radius, and also the inter-ion distance is comparatively big.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the similar dimensions of these chemical elements nearly one hundred% of Yb-doping might be obtained.
Though ytterbium-doped laser gain media usually exhibit a little quantum defect, ytterbium-doped tungstates allow for especially little values. As an example, a 1030-nm Yb:YAG laser would Usually be pumped all around 940 nm, whereas Yb:KGW or Yb:KYW might be most efficiently pumped around 981 nm.
This tandem of characteristics has considerably-reaching implications, specially in the development of compact nevertheless powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at home temperature had been measured. The emission spectrum and life time with the three File four excited state had been established. Employing typical and modified Judd–Ofelt theories, the depth parameters plus the radiative lifetimes were being calculated and superior settlement Using the experimental outcomes was obtained for both theories.
