This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers getting fiber output. To prevent spectral narrowing during amplification as well as corresponding lengthening with the amplified pulse when it truly is compressed, a combination of two Yb:KYW crystals ended up employed, Using the spectral maxima with the amplification shifted relative to one another and with spectral profiling with the amplified radiation.

In advance of the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It absolutely was in reality Employed in the first continually working crystal laser.

Raman, luminescence and transmission spectra reveal optical capabilities owing into the existence of thulium ions, and as a consequence the materials might be further more studied within the scope of laser and luminescence programs.

A large brightnessQ-switched oscillator and regenerative amplifier determined by a dual-crystal Yb:KGW laser

... at fifty percent-height were being produced within a master oscillator with selfsynchronization of the axial modes, described inside our previously article. 21 The new edition of the laser, in contrast to that described in our previously article, employed an Yb:KYW crystal by having an N pcut (optical axis N p on the index ellipsoid was parallel on the propagation path with the laser radiation), Along with the polarization from the created radiation directed alongside the N m axis.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the very similar measurements of those chemical aspects around one hundred% of Yb-doping might be realized.

When ytterbium-doped laser gain media typically exhibit a small quantum defect, ytterbium-doped tungstates make it possible for for particularly modest values. Such as, a 1030-nm Yb:YAG laser would Typically be pumped around 940 nm, While Yb:KGW or Yb:KYW can be most effectively pumped around 981 nm.

Li2WO4-WO3 flux was correctly applied lowering The expansion temperature down below 900 oC. In accordance with solitary crystal x-ray measurements, the crystal corresponds to your P2/n House team.
