The achieve bandwidth e.g. of Yb:KGW and Yb:KYW may be very large in contrast with that of Yb:YAG. This allows for broad wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values perfectly down below one hundred fs are already attained 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 an essential position in laser technological know-how. Its Main operate should be to generate ultrashort pulses of light, spanning just some hundred femtoseconds.
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the heart beat
FIG. four. Autocorrelation operate of the pulse 共a兲and spectrum 共b兲of a laser with a rectangular Lively ingredient for an output ability of seven hundred mW. The width of
Ultrafast lasers, with pulse widths of some picoseconds (ten−twelve s) or significantly less, enable time resolution necessary in laser-excited fluorescence life span spectroscopy and imaging approaches.What's more, they deliver substantial pulse peak powers at significant repetition fees and reasonable common output powers.
The monoclinic crystal constructions brings about a natural birefringence, helping to prevent thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical characteristics owing to the presence of thulium ions, and thus the products may be further studied from the scope of laser and luminescence apps.
A significant brightnessQ-switched oscillator and regenerative amplifier based on a dual-crystal Yb:KGW laser
For tungstates, the ytterbium doping concentration can be quite high with no substantial quenching since the replaced ions have an extremely related ion radius, and the inter-ion length is relatively huge.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW mainly because of the similar dimensions of those chemical components as much as a hundred% of Yb-doping may very well be reached.
The thermal conductivity of widespread double tungstates is from the buy to 3–four W/(K m) �?which is not terrible in contrast with other laser crystals (although various moments under for YAG), and quite huge website when compared with the thermal conductivity of standard Eyeglasses.
There isn't any objects in the cart. Add things to the cart and ask for an official estimate or purchase on the net Subtotal
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, can be a amazing substance that plays a vital position in laser technological know-how. Its Most important perform is to deliver ultrashort pulses of light, spanning just some hundred femtoseconds.
Ask RP Photonics for almost any suggestions about tungstate lasers, which includes femtosecond lasers and high-electricity lasers.
