When ytterbium-doped laser achieve media usually exhibit a small quantum defect, ytterbium-doped tungstates let for specifically small values. For instance, a 1030-nm Yb:YAG laser would Typically be pumped all around 940 nm, While Yb:KGW or Yb:KYW could possibly be most competently pumped around 981 nm.

In the future, an investigation about the spectral attain curve of Yb:KGW in the principle amplifier will be carried out under cryogenic temperature evolution from 77 K to 300 K. The working temperature are going to be controlled to appreciate broader obtain bandwidth and less shift for the central wavelength of the primary amplifier.

In addition to its use like a Raman crystal, KGW can also be used in other optical programs, which include in laser devices and being a scintillator in medical imaging.

In distinction, the seed laser could be amplified to more than one mJ beneath the orthogonal orientation configuration.

Amplified pulses having an Vitality previously mentioned two.5 mJ is often expected by making use of a greater pump electrical power to the regenerative amplifier and which makes it get the job done within the saturation level. The laser fluence of ~1 J/cm2 about the dichroic mirrors is considered to be beneath the injury threshold of higher-top quality dielectric-coated mirrors.

The black line denotes the configuration With all the crystals positioned in exactly the same orientation, whilst the red line is underneath the configuration of crystals put in orthogonal orientation.

]. This process was according to The point that the spectral emission cross-segment curves differ from each other when laser polarization is paralleled to the different optical axis of Yb-doped double tungstates[
