The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is very huge as opposed with that of Yb:YAG. This permits for wide wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values very well underneath a hundred fs are actually achieved with passive manner locking.

The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a extraordinary material that plays an important role in laser technologies. Its Main perform is always to create ultrashort pulses of light, spanning just a few hundred femtoseconds.

We present a dual-crystal Yb:KGW laserthat iscapable to operate as a Q-switched oscillator with output energy around 24 W and pulse size of 20 ns,or as a regenerative amplifier with output power up to 21 W and pulse duration down below two hundred fs immediately after compression of chirped pulses. Both equally lasers have superb beam quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with direct longitudinal pumping by powerful linear arrays of semiconductor injection lasers possessing fiber output. To prevent spectral narrowing throughout amplification and also the corresponding lengthening of your amplified pulse when it can be compressed, a combination of two Yb:KYW crystals were applied, With all the spectral maxima of the amplification shifted relative to one another and with spectral profiling from the amplified radiation.

The monoclinic crystal structures results in a natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization loss.

Raman, luminescence and transmission spectra reveal optical options owing into the presence of thulium ions, and thus the components could be more analyzed within the scope of laser and luminescence programs.

Spatial structure of the beam as well as corresponding depth profiles I with the output on the laser.

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW mainly because of the very similar measurements of such chemical things approximately 100% of Yb-doping can be realized.

Although ytterbium-doped laser achieve media commonly show a little quantum defect, ytterbium-doped tungstates make it possible for for significantly smaller values. Such as, a 1030-nm Yb:YAG laser would Ordinarily be pumped all-around 940 nm, Whilst Yb:KGW or Yb:KYW may be most more info proficiently pumped close to 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is actually a exceptional materials that plays an important job in laser technology. Its Most important purpose is always to produce ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
