For some programs, tungstates give a combination of various valuable Attributes. Particularly for passive mode locking, ytterbium-doped double tungstates are sometimes excellent to other media when it comes to The mix of substantial achieve bandwidth, huge cross-sections, and comparatively excellent thermal Qualities �?While in Each and every unique self-discipline much better materials could be uncovered.
In addition to its use like a Raman crystal, KGW is usually Utilized in other optical programs, including in laser programs and for a scintillator in clinical imaging.
The datasets used and/or analysed during the current analyze offered through the corresponding author on acceptable request.
Amplified pulses by having an energy earlier mentioned two.five mJ is often expected by applying a greater pump energy to the regenerative amplifier and which makes it perform at the saturation stage. The laser fluence of ~1 J/cm2 around the dichroic mirrors is believed being below the destruction threshold of significant-good quality dielectric-coated mirrors.
Nevertheless, as soon as Nd3+:YAG turned commercially readily available, the curiosity in CaWO4 dropped sharply. In read more afterwards a long time, sure other tungstate crystals started to bring in lots of interest.
The black line denotes the configuration Along with the crystals positioned in precisely the same orientation, while the red line is underneath the configuration of crystals positioned in orthogonal orientation.
Therefore, with an extra advancement inside our regenerative amplifier, 2 mJ compressed pulses might be anticipated, with out detrimental any component inside our compressor.
Determine four Beam radius variation on the two crystals whilst modifying the focal duration with the thermal lensing influence.

A multi-go key amplifier will further more Improve the Electricity to above forty mJ. We're going to apply cryogenically cooled Yb:KGW technological know-how to restrain the thermal effect. Two levels of compression is going to be used after amplification. The very first stage consists of a typical Treacy-style compressor, and could compress the heart beat length to down below three hundred fs with an effectiveness of roughly 70%. The next stage includes a gasoline-filled multi-move mobile[

The two energies are marked from the dashed strains and their values are labeled within the plots. The equivalent capabilities had been also noticed in KGW and YAG crystals, whose spectral broadening dynamics are shown for just a comparison in Fig. 4.
