In realistic conditions, the Yb:KYW crystal has discovered its niche in high-power laser purposes as a consequence of its capacity to make substantial Vitality ultrashort laser pulses whilst protecting a compact sizing. The interplay of its attributes �?seamless ytterbium substitution, sturdy absorption attributes, ultrashort pulse generation and efficiency in energy conversion �?positions the Yb:KYW crystal for a cornerstone while in the laser engineering, covering diverse fields starting from scientific analysis to industrial purposes.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is a impressive product that plays a crucial job in laser technologies. Its Principal purpose would be to make ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the heart beat
FIG. 4. Autocorrelation perform of the heartbeat 共a兲and spectrum 共b兲of the laser with a rectangular active ingredient for an output ability of seven-hundred mW. The width of
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the identical measurements of these chemical elements nearly one hundred% of Yb-doping could possibly be achieved. This one of a kind attribute permits ytterbium to take the put of yttrium with almost no disruption towards the crystal’s lattice.
Prior to the development of Nd:YAG, Nd3+:CaWO4 was a vital rare-earth-doped laser achieve medium. It absolutely was actually Utilized in the main constantly working crystal laser.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and they are used as lasing supplies to produce ultrashort (~ 100-200 fs) higher energy pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser methods.
Spatial construction in the beam plus the corresponding depth profiles I at the output of the laser.
For tungstates, the ytterbium doping focus can be quite high without the need of major quenching since the changed ions have an exceptionally comparable ion radius, along with the inter-ion distance is pretty huge.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW because of the similar sizes of these chemical components as much as a hundred% of Yb-doping may very well be realized.
When ytterbium-doped laser obtain media frequently exhibit a little quantum defect, ytterbium-doped tungstates permit for specially little values. One example is, a 1030-nm Yb:YAG laser would Usually be pumped all over 940 nm, whereas Yb:KGW or Yb:KYW could possibly be most competently pumped all around 981 nm.
