The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This allows for extensive wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values properly underneath a hundred fs are actually accomplished with passive mode locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is usually a outstanding content that performs a very important function in laser engineering. Its primary function would be to create ultrashort pulses of light, spanning only a few hundred femtoseconds.
We existing a dual-crystal Yb:KGW laserthat iscapable to operate being a Q-switched oscillator with output energy nearly 24 W and pulse duration of twenty ns,or as a regenerative amplifier with output power approximately 21 W and pulse length below two hundred fs following compression of chirped pulses. Equally lasers have great beam good quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, ensuring efficient energy conversion and high overall performance in laser techniques.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW because of the related measurements of those chemical things nearly a hundred% of Yb-doping could be accomplished. This distinctive characteristic permits ytterbium to go ahead and take position of yttrium with nearly no disruption for the crystal’s lattice.
Right after air drying and subsequent cleaning using a cotton fabric soaked in Liquor, the movie surface showed no signs of peeling or scratches.

Substantial-electric power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes
Though ytterbium-doped laser achieve media commonly show a little quantum defect, ytterbium-doped tungstates make it possible for for significantly compact values. For example, a 1030-nm Yb:YAG laser would Usually be pumped close to 940 nm, whereas Yb:KGW or Yb:KYW might be most efficiently pumped around 981 nm.
Li2WO4-WO3 flux was productively used reducing the growth temperature under 900 oC. In keeping with single crystal x-ray measurements, the crystal corresponds for the P2/n Room group.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at space temperature have been calculated. The emission get more info spectrum and lifetime on the three File four energized point out ended up decided. Utilizing common and modified Judd–Ofelt theories, the depth parameters as well as radiative lifetimes were calculated and great agreement With all the experimental benefits was received for equally theories.
Check with RP Photonics for just about any advice relating to tungstate lasers, such as femtosecond lasers and significant-electrical power lasers.
