The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is rather substantial when compared with that of Yb:YAG. This enables for extensive wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values effectively under 100 fs have been attained with passive mode locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is often a remarkable materials that plays a very important function in laser technological innovation. Its Principal purpose is to generate ultrashort pulses of light, spanning just some hundred femtoseconds.
time. Crystals on the compound melts congruently at 1007 oC, nonetheless soften crystallization of top quality crystal is not possible due to period transition at ~920 oC. The highest seeded Answer process from

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW mainly because of the similar dimensions of such chemical components as much as 100% of Yb-doping can be accomplished. This one of a kind characteristic permits ytterbium to take the put of yttrium with pretty much no disruption towards the crystal’s lattice.
Right after air drying and subsequent cleaning by using a cotton fabric soaked in Liquor, the film area showed no indications of peeling or scratches.
FIG. one. Optical format of a laser with immediate pumping Using the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output
Spatial structure with the beam as well as the corresponding intensity profiles I at click here the output of your laser.

Nevertheless, after Nd3+:YAG grew to become commercially offered, the desire in CaWO4 dropped sharply. In later on a long time, particular other tungstate crystals began to entice many awareness.
Though ytterbium-doped laser gain media frequently exhibit a small quantum defect, ytterbium-doped tungstates permit for notably tiny values. As an example, a 1030-nm Yb:YAG laser would Usually be pumped around 940 nm, whereas Yb:KGW or Yb:KYW can be most successfully pumped about 981 nm.
Li2WO4-WO3 flux was productively applied lowering the growth temperature under 900 oC. In keeping with one crystal x-ray measurements, the crystal corresponds to your P2/n space team.
