In sensible terms, the Yb:KYW crystal has uncovered its specialized niche in substantial-power laser apps resulting from its capacity to create higher energy ultrashort laser pulses when keeping a compact dimension. The interaction of its characteristics �?seamless ytterbium substitution, robust absorption traits, ultrashort pulse technology and effectiveness in Power conversion �?positions the Yb:KYW crystal to be a cornerstone within the laser technology, covering numerous fields ranging from scientific research to industrial apps.
The comparison with Eyeglasses is suitable Considering that the big attain bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We current a dual-crystal Yb:KGW laserthat iscapable to function to be a Q-switched oscillator with output power approximately 24 W and pulse length of 20 ns,or as a regenerative amplifier with output energy nearly 21 W and pulse length beneath 200 fs after compression of chirped pulses. Both of those lasers have great beam top quality with beam parameter M2

Ultrafast lasers, with pulse widths of some picoseconds (ten−twelve s) or much less, permit enough time resolution expected in laser-excited fluorescence lifetime spectroscopy and imaging strategies.Additionally, they supply significant pulse peak powers at superior repetition prices and moderate typical output powers.
Prior to the event of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser get medium. It was in reality Utilized in the first continually running crystal laser.
Raman, luminescence and transmission spectra reveal optical attributes owing into the existence of thulium ions, and thus the products may very well be even more examined during the scope of laser and luminescence apps.
Spatial framework of the beam plus the corresponding depth profiles I at the output in the laser.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to comparable sizes of these chemical elements around a hundred% of Yb-doping may very well be attained.
The thermal conductivity of popular double tungstates is of your buy to 3–four W/(K m) �?which isn't poor compared with other laser crystals (While many occasions fewer than for YAG), and reasonably big as opposed Along with the thermal conductivity of common Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is usually a extraordinary product that performs a crucial part in laser engineering. Its Main function should be to make ultrashort pulses of light, spanning just some hundred femtoseconds.
Ask RP Photonics for almost any suggestions about tungstate lasers, like femtosecond lasers and higher-ability lasers.
