In simple terms, the Yb:KYW crystal has observed its niche in large-ability laser programs resulting from its power to generate substantial Power ultrashort laser pulses whilst retaining a compact dimension. The interplay of its characteristics �?seamless ytterbium substitution, strong absorption attributes, ultrashort pulse technology and effectiveness in Power conversion �?positions the Yb:KYW crystal as being a cornerstone during the laser technological know-how, covering varied fields ranging from scientific investigation to industrial apps.
The comparison with Eyeglasses is suitable since the massive gain bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We current a twin-crystal Yb:KGW laserthat iscapable to work as being a Q-switched oscillator with output electrical power nearly 24 W and pulse size of twenty ns,or as being a regenerative amplifier with output energy as many as 21 W and pulse period below 200 fs soon after compression of chirped pulses. Each lasers have excellent beam high-quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Exhibit robust peaks at 980 nm and 1030 nm, respectively, making sure successful Vitality conversion and superior efficiency in laser systems.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the very similar measurements of these chemical elements nearly 100% of Yb-doping could be reached. This exclusive attribute permits ytterbium to take the put of yttrium with nearly no disruption towards the crystal’s lattice.
The monoclinic crystal constructions ends in a pure birefringence, assisting to prevent thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and they are made use of as lasing materials to create ultrashort (~ a hundred-200 fs) higher electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser techniques.
Spatial construction of your beam as well as the corresponding depth profiles I on the output of your laser.

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to equivalent dimensions of those chemical elements around one hundred% of Yb-doping can be reached.
The thermal conductivity of common double tungstates is from the order to 3–four W/(K m) �?which is not bad as opposed with other laser crystals (Though several periods less than for YAG), and quite significant in comparison With all the thermal conductivity of usual glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is often a impressive materials that read more plays a significant purpose in laser engineering. Its primary perform will be to generate ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Question RP Photonics for just about any information relating to tungstate lasers, such as femtosecond lasers and superior-electricity lasers.
