The attain bandwidth e.g. of Yb:KGW and Yb:KYW is rather massive in comparison with that of Yb:YAG. This permits for wide wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values well underneath one hundred fs happen to be obtained with passive method locking.
The very first two peaks might be connected with luminescence of pure material59, whilst the remaining peaks could be attributed to the luminescence of unknown dopants, Even though the supplier specified the sample as undoped. The luminescence of YAG crystal produces strong UV luminescence with a utmost intensity at 300 nm, which is attributed to put together self-trapped exciton and antisite defect-linked emissions60. Eventually, no luminescence inside the UV, visible and in the vicinity of-IR was observed in KGW and LT crystals, at the very least within the detection choice of fiber spectrometer (200�?00 nm).
The check here datasets employed and/or analysed in the course of the current review offered in the corresponding writer on fair ask for.
For tungstates, the ytterbium doping concentration can be quite significant without significant quenching because the changed ions have an exceedingly comparable ion radius, as well as the inter-ion distance is comparatively huge.
A number of approaches are already adopted to resolve this issue. An acousto-optical programmable dispersive filter may be utilized to modulate the seed’s spectrum to suppress the get-narrowing influence[
KGW (potassium gadolinium tungstate) is actually a crystal that is often employed for a Raman crystal in Raman spectroscopy. It's really a colorless, clear crystal that has a higher Raman scattering efficiency and a powerful Raman spectrum, rendering it suitable for A variety of Raman programs.
Ask RP Photonics for almost any tips concerning tungstate lasers, which include femtosecond lasers and large-energy lasers.

A multi-pass main amplifier will further boost the Electrical power to higher than forty mJ. We'll use cryogenically cooled Yb:KGW technologies to restrain the thermal effect. Two levels of compression might be utilized just after amplification. The main phase requires a common Treacy-style compressor, and will compress the pulse period to underneath 300 fs having an effectiveness of around 70%. The 2nd phase entails a fuel-stuffed multi-go cell[
