In sensible terms, the Yb:KYW crystal has located its area of interest in superior-ability laser applications resulting from its capacity to produce superior Power ultrashort laser pulses though preserving a compact dimension. The interplay of its capabilities �?seamless ytterbium substitution, potent absorption traits, ultrashort pulse technology and effectiveness in Vitality conversion �?positions the Yb:KYW crystal for a cornerstone while in the laser technologies, masking numerous fields ranging from scientific study to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is often a outstanding substance that performs an important part in laser know-how. Its Principal functionality should be to deliver ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing inside of a regenerative amplifier by spectral profiling of the pulse
FIG. four. Autocorrelation operate of the heart beat 共a兲and spectrum 共b兲of a laser with an oblong Lively element for an output ability of 700 mW. The width of
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW because of the related measurements of such chemical factors as much as 100% of Yb-doping may be realized. This unique attribute permits ytterbium to go ahead and take spot of yttrium with just about no disruption into the crystal’s lattice.
Before the event of Nd:YAG, Nd3+:CaWO4 was a very important exceptional-earth-doped laser acquire medium. It absolutely was actually Utilized in the main continuously running crystal laser.
Raman, luminescence and transmission spectra expose optical capabilities owing to your existence of thulium ions, and so the components might be further examined while in the scope of laser and luminescence programs.
Spatial structure of your beam as well as corresponding intensity profiles I at the output of the laser.
EKSMA Optics uses cookies to supply you with the greatest buying encounter. If you continue on to utilize our solutions, We'll assume you agree to the usage of these types of cookies.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of related dimensions of such chemical elements around 100% of Yb-doping could be realized.
As a consequence of Earlier detected malicious actions which originated through the network you might be employing, please ask for unblock to website.
This tandem of attributes has much-achieving implications, particularly in the construction of compact still powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at home temperature were measured. The emission spectrum and lifetime on the three File four energized point out were determined. Making use of common and modified Judd–Ofelt theories, the intensity parameters along with the radiative lifetimes ended up calculated and fantastic arrangement read more Together with the experimental effects was received for equally theories.
