The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is actually a exceptional substance that performs a significant function in laser technologies. Its Principal function is to produce ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the pulse
The absorption and emission spectra of Yb:KYW Crystals display strong peaks at 980 nm and 1030 nm, respectively, ensuring effective Strength conversion and large overall performance in laser devices.
Ultrafast lasers, with pulse widths of a few picoseconds (ten−12 s) or significantly less, empower some time resolution demanded in laser-fired up fluorescence life span spectroscopy and imaging techniques.In addition, they produce substantial pulse peak powers at significant repetition prices and average average output powers.
Right before the development of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser obtain medium. It was in reality Employed in the very first continually functioning crystal laser.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and they are used as lasing supplies to create ultrashort (~ one hundred-200 fs) large electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser methods.
Tungstates are likely to possess large Raman coefficients (�?Raman scattering). Thus, they can produce considerable Raman achieve at reasonable optical intensities. It is achievable to make use of the laser crystal by itself for a Raman converter.

Nonetheless, after Nd3+:YAG grew to become commercially out there, the desire in CaWO4 dropped sharply. In afterwards years, particular other tungstate crystals started to appeal to a lot of awareness.
