The get bandwidth e.g. of Yb:KGW and Yb:KYW is quite significant in comparison with that of Yb:YAG. This permits for broad wavelength tunability and for much shorter pulse durations from method-locked lasers. Values very well below 100 fs are accomplished with passive mode locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is actually a amazing content that performs a very important position in laser technologies. Its Key function is always to deliver ultrashort pulses of light, spanning just some hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light-weight absorption at about 981 nm will make the crystal well suited for diode pumping. It can be further enhanced by its extraordinary efficiency in this process, coupled with its lower quantum defect.

Ultrafast lasers, with pulse widths of some picoseconds (ten−12 s) or considerably less, permit enough time resolution essential in laser-energized fluorescence life time spectroscopy and imaging tactics.What's more, they supply substantial pulse peak powers at substantial repetition charges and moderate normal output powers.
Before the event of Nd:YAG, Nd3+:CaWO4 was a vital unusual-earth-doped laser gain medium. It had been in actual fact used in the main continually functioning crystal laser.

For tungstates, the ytterbium doping concentration can be quite superior with out significant quenching since the changed ions have an incredibly similar ion radius, along with the inter-ion length is relatively huge.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to the similar dimensions of those chemical elements nearly one hundred% of Yb-doping could possibly be accomplished.
While ytterbium-doped laser obtain media normally exhibit a small quantum defect, ytterbium-doped tungstates enable for notably smaller values. For example, a 1030-nm Yb:YAG laser would normally be pumped all over 940 nm, While Yb:KGW or Yb:KYW can be most efficiently pumped around 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is often a impressive content that plays a vital position in laser technological know-how. Its Major operate is always to produce ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
