In practical conditions, the Yb:KYW crystal has located its market in large-electric power laser apps on account of its ability to generate large Vitality ultrashort laser pulses whilst maintaining a compact dimensions. The interplay of its attributes �?seamless ytterbium substitution, potent absorption features, ultrashort pulse generation and performance in Vitality conversion �?positions the Yb:KYW crystal as a cornerstone from the laser technological innovation, covering assorted fields ranging from scientific research to industrial apps.
The comparison with glasses is suitable Considering that the big achieve bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We existing a twin-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electricity up to 24 W and pulse length of 20 ns,or for a regenerative amplifier with output electricity up to 21 W and pulse length down below 200 fs soon after compression of chirped pulses. Equally lasers have excellent beam high-quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Screen solid peaks at 980 nm and 1030 nm, respectively, making sure effective Electricity conversion and substantial overall performance in laser systems.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to the related measurements of such chemical things as much as a hundred% of Yb-doping can be accomplished. This exclusive characteristic permits ytterbium to go ahead and take location of yttrium with just about no disruption on the crystal’s lattice.
Adhesion Exam Compliant with MIL-C-675C armed forces expectations, an adhesion examination included implementing a tape that fulfills LT-ninety requirements onto the lens movie layer. The tape was affixed thoroughly after which you can eliminated vertically. This method was performed thrice, leading to no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are applied as lasing products to create ultrashort (~ 100-two hundred fs) large electricity pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser techniques.
Tungstates are likely to own superior Raman coefficients (�?Raman scattering). Thus, they're able to deliver substantial Raman achieve at reasonable optical intensities. It can be done to use the laser crystal by itself for a Raman converter.
... at fifty percent-peak were being created in a master oscillator with selfsynchronization from the axial modes, explained inside our previously write-up. 21 The new edition with the laser, contrary to that explained in our before posting, employed an Yb:KYW crystal having an N pcut (optical axis N p on the index ellipsoid was parallel for the propagation route from the laser radiation), with the polarization with the generated radiation directed together the N m axis.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to very similar measurements of these chemical factors approximately one hundred% of Yb-doping might be achieved.
