The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is really a extraordinary content that performs an essential job in laser technological innovation. Its Most important operate should be to make ultrashort pulses of light, spanning just a couple hundred femtoseconds.

Ultrafast lasers, with pulse widths of a few picoseconds (10−12 s) or fewer, empower the time resolution required in laser-enthusiastic fluorescence life time spectroscopy and imaging procedures.Also, they deliver higher pulse peak powers at large repetition fees and average average output powers.
Right before the development of Nd:YAG, Nd3+:CaWO4 was a vital exceptional-earth-doped laser obtain medium. It had been the truth is Employed in the initial repeatedly functioning crystal laser.
Raman, luminescence and transmission spectra reveal optical functions owing towards the presence of thulium ions, and therefore the components may very well be even further researched from the scope of laser and luminescence apps.

On the other hand, as soon as Nd3+:YAG turned commercially readily available, the interest in CaWO4 dropped sharply. In later on several years, specific other tungstate crystals started to bring in loads of interest.
The thermal conductivity of common double tungstates is with the order to 3–4 W/(K m) �?which is not undesirable compared with other laser crystals (Whilst a number of instances under for YAG), and relatively huge in contrast Using the thermal conductivity of standard glasses.
This tandem of attributes has much-achieving implications, particularly in the development of compact nonetheless powerfull lasers.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is a outstanding product that plays a crucial job in laser know-how. Its Main purpose would be to generate ultrashort pulses of light, spanning just a few hundred femtoseconds.
Question RP Photonics for just about any assistance about tungstate lasers, which include femtosecond lasers and superior-ability lasers.
