The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is usually a exceptional content that plays a very important job in laser technologies. Its Key perform is always to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.

The absorption and emission spectra of Yb:KYW Crystals display robust peaks at 980 nm and 1030 nm, respectively, guaranteeing successful Electricity conversion and superior performance in laser systems.

Ultrafast lasers, with pulse widths of a few picoseconds (ten−12 s) or much less, allow time resolution necessary in laser-fired up fluorescence lifetime spectroscopy and imaging methods.Moreover, they produce superior pulse peak powers at significant repetition costs and moderate typical output powers.

Prior to the event of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser gain medium. It had been in actual fact used in the 1st continuously functioning crystal laser.

Tungstates are likely to have higher Raman coefficients (�?Raman scattering). As a result, they will crank out sizeable Raman attain at average optical intensities. It is achievable to make use of the laser crystal itself as being a Raman converter.

... Not only the position of crystal within the cavity but additionally the amplification axis of crystal impacts the laser operation greatly, as the absorption and emission cross sections with the crystal are really various based on the orientation in the crystal.

The thermal conductivity of prevalent double tungstates is with the order to 3–four W/(K m) �?which isn't negative as opposed with other laser crystals (Despite the fact that several moments less than for YAG), and relatively significant in contrast With all the thermal conductivity of regular glasses.

Li2WO4-WO3 flux was properly used reducing the growth temperature below 900 oC. In line with solitary crystal x-ray measurements, the crystal corresponds to your website P2/n space group.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is actually a exceptional content that plays an important job in laser technology. Its Most important purpose is usually to produce ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.

At the same time, a shorter laser wavelength is often received; it can be done to work by using a quantum defect nicely down below 1%. To be a consequence, the heat technology could be so compact that this partly compensates the decreased thermal conductivity.
