In practical phrases, the Yb:KYW crystal has located its market in higher-energy laser purposes as a consequence of its capability to create substantial Strength ultrashort laser pulses even though keeping a compact dimension. The interaction of its characteristics �?seamless ytterbium substitution, solid absorption traits, ultrashort pulse era and effectiveness in Electrical power conversion �?positions the Yb:KYW crystal being a cornerstone in the laser know-how, masking varied fields starting from scientific study to industrial apps.
The comparison with Eyeglasses is appropriate For the reason that significant acquire 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 for a Q-switched oscillator with output power approximately 24 W and pulse length of 20 ns,or as being a regenerative amplifier with output electricity approximately 21 W and pulse length beneath 200 fs following compression of chirped pulses. The two lasers have outstanding beam top quality with beam parameter M2
FIG. four. Autocorrelation operate of the pulse 共a兲and spectrum 共b兲of the laser with an oblong Lively factor for an output energy of seven-hundred mW. The width of
Ultrafast lasers, with pulse widths of a few picoseconds (10−twelve s) or fewer, help some time resolution demanded in laser-enthusiastic fluorescence life span spectroscopy and imaging approaches.What's more, they supply substantial pulse peak powers at large repetition charges and moderate ordinary output powers.
Right before the development of Nd:YAG, Nd3+:CaWO4 was a very important rare-earth-doped laser achieve medium. It absolutely was in reality Employed in the very first repeatedly functioning crystal laser.
Raman, luminescence and transmission spectra reveal optical capabilities owing to the presence of thulium ions, and so the products could be additional researched inside the scope of laser and luminescence purposes.
A superior brightnessQ-switched oscillator and regenerative amplifier determined by a twin-crystal Yb:KGW laser

High-electricity repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for more info technological and biomedical programs
Although ytterbium-doped laser achieve media commonly exhibit a small quantum defect, ytterbium-doped tungstates permit for specifically compact values. For example, a 1030-nm Yb:YAG laser would Usually be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could be most efficiently pumped around 981 nm.
Li2WO4-WO3 flux was efficiently used decreasing the growth temperature underneath 900 oC. Based on solitary crystal x-ray measurements, the crystal corresponds to your P2/n space group.
