In useful conditions, the Yb:KYW crystal has uncovered its market in significant-electric power laser apps on account of its capability to generate high Electricity ultrashort laser pulses even though preserving a compact dimension. The interaction of its characteristics �?seamless ytterbium substitution, robust absorption traits, ultrashort pulse technology and performance in Strength conversion �?positions the Yb:KYW crystal being a cornerstone in the laser know-how, covering varied fields starting from scientific study to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is usually a exceptional materials that performs a crucial function in laser technological innovation. Its Key operate should be to crank out ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser dependant on Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the heart beat
Color-coded reflectivity of a Bragg mirror as a perform of wavelength and angle from the incident beam.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW a result of the similar sizes of such chemical elements approximately a hundred% of Yb-doping may very well be reached. This exclusive characteristic permits ytterbium to take the location of yttrium with pretty much no disruption on the crystal’s lattice.
Just after air drying and subsequent cleaning which has a cotton cloth soaked in Alcoholic beverages, the film surface area confirmed no signs of peeling or scratches.
FIG. one. Optical format of a laser with direct pumping Along with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output
A high brightnessQ-switched oscillator and regenerative amplifier dependant on a dual-crystal Yb:KGW laser
... at 50 %-peak click here were being created inside a grasp oscillator with selfsynchronization with the axial modes, explained inside our before article. 21 The new version of the laser, not like that explained within our before posting, employed an Yb:KYW crystal by having an N pcut (optical axis N p with the index ellipsoid was parallel into the propagation direction of the laser radiation), With all the polarization on the produced radiation directed alongside the N m axis.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW a result of the similar sizes of these chemical factors around one hundred% of Yb-doping may very well be reached.
