In practical terms, the Yb:KYW crystal has found its niche in high-power laser applications because of its capacity to make high Strength ultrashort laser pulses although protecting a compact sizing. The interplay of its capabilities �?seamless ytterbium substitution, solid absorption features, ultrashort pulse era and effectiveness in energy conversion �?positions the Yb:KYW crystal as being a cornerstone within the laser know-how, masking varied fields starting from scientific investigation to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is actually a amazing content that plays an essential role in laser know-how. Its Major functionality should be to make ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
We present a dual-crystal Yb:KGW laserthat iscapable to operate as a Q-switched oscillator with output electrical power approximately 24 W and pulse duration of twenty ns,or like a regenerative amplifier with output ability as many as 21 W and pulse length down below two hundred fs just after compression of chirped pulses. Each lasers have fantastic beam top quality with beam parameter M2
Coloration-coded reflectivity of the Bragg mirror as a functionality of wavelength and angle on the incident beam.
By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of equivalent dimensions of these chemical things approximately 100% of Yb-doping may very well be reached. This special attribute permits ytterbium to take the put of yttrium with almost no disruption to the crystal’s lattice.
Soon after air drying and subsequent cleaning using a cotton fabric soaked in Liquor, the film surface area confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and therefore are utilised as lasing elements to create ultrashort (~ a hundred-200 fs) higher ability pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser devices.
Tungstates are likely to possess higher Raman coefficients (�?Raman scattering). Hence, they could generate significant Raman get at reasonable optical intensities. It is possible to use the laser crystal by itself as more info being a Raman converter.
For tungstates, the ytterbium doping focus can be quite substantial with no major quenching since the replaced ions have a very similar ion radius, as well as inter-ion length is comparatively massive.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the very similar measurements of those chemical things nearly one hundred% of Yb-doping might be achieved.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is usually a amazing content that plays a crucial role in laser technologies. Its primary functionality is always to create ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Inquire RP Photonics for virtually any suggestions about tungstate lasers, which includes femtosecond lasers and superior-energy lasers.
