The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is usually a exceptional product that performs a crucial purpose in laser technology. Its Key function is usually to make ultrashort pulses of light, spanning just a couple hundred femtoseconds.
The Yb:KYW crystal’s proficiency in gentle absorption at close to 981 nm tends to make the crystal well suited for diode pumping. It can be additional Increased by its outstanding performance in this process, coupled with its lower quantum defect.

Ultrafast lasers, with pulse widths of a few picoseconds (ten−12 s) or considerably less, enable enough time resolution needed in laser-energized fluorescence lifetime spectroscopy and imaging strategies.What's more, they supply higher pulse peak powers at substantial repetition rates and reasonable normal output powers.
After air drying and subsequent cleansing having a cotton cloth soaked in alcohol, the movie floor confirmed no indications of peeling or scratches.
