The attain bandwidth e.g. of Yb:KGW and Yb:KYW may be very significant compared with that of Yb:YAG. This allows for extensive wavelength tunability and for Significantly shorter pulse durations from mode-locked lasers. Values perfectly below 100 fs are already realized with passive mode locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, can be a impressive content that performs an important position in laser technological innovation. Its Major perform is to deliver ultrashort pulses of light, spanning just a few hundred femtoseconds.
The Yb:KYW crystal’s proficiency in light-weight absorption at all-around 981 nm would make the crystal like minded for diode pumping. It really is even more Increased by its exceptional effectiveness in this method, coupled with its reduced quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Exhibit robust peaks at 980 nm and 1030 nm, respectively, making certain effective Power conversion and large efficiency in laser systems.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW a result of the similar dimensions of these chemical factors as much as a hundred% of Yb-doping may be reached. This special attribute permits ytterbium to take the put of yttrium with just about no disruption to the crystal’s lattice.
The monoclinic crystal structures ends in a natural birefringence, helping to steer clear of thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra reveal optical options owing into the presence of thulium ions, and get more info thus the products may very well be even more studied from the scope of laser and luminescence purposes.
Tungstates are likely to get superior Raman coefficients (�?Raman scattering). As a result, they can create considerable Raman gain at average optical intensities. It can be done to utilize the laser crystal by itself as being a Raman converter.
EKSMA Optics employs cookies to provde the most effective procuring working experience. In case you proceed to use our companies, we will presume that you simply comply with the use of these cookies.
... Not simply the situation of crystal while in the cavity but additionally the amplification axis of crystal has an effect on the laser operation tremendously, as the absorption and emission cross sections from the crystal are very distinctive based on the orientation of your crystal.
Resulting from Earlier detected destructive actions which originated from the network you are making use of, please request unblock to internet site.
This tandem of attributes has far-achieving implications, notably in the construction of compact nevertheless powerfull lasers.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is really a impressive product that performs a crucial job in laser know-how. Its Most important purpose will be to crank out ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
Here you are able to post inquiries and responses. As far as they get approved with the creator, they may seem above this paragraph together with the author’s remedy. The author will choose acceptance based on selected criteria. In essence, The difficulty needs to be of sufficiently wide interest.
