The 1st two peaks can be associated with luminescence of pure material59, though the remaining peaks could be attributed on the luminescence of unidentified dopants, although the provider specified the sample as undoped. The luminescence of YAG crystal generates powerful UV luminescence using a highest intensity at three hundred nm, which can be attributed to combined self-trapped exciton and antisite defect-relevant emissions60. Eventually, no luminescence in the UV, seen and close to-IR was noticed in KGW and LT crystals, at the very least inside the detection number of fiber spectrometer (200�?00 nm).
In distinction, the seed laser can be amplified to in excess of one mJ under the orthogonal orientation configuration.
Amplified pulses using an Vitality earlier mentioned 2.5 mJ could be envisioned by applying an increased pump electricity to your regenerative amplifier and rendering it operate on the saturation degree. The laser fluence of ~1 J/cm2 on the dichroic mirrors is thought to generally be underneath the damage threshold of substantial-high-quality dielectric-coated mirrors.

The black line denotes the configuration Using the crystals positioned in precisely the same orientation, although the pink line is beneath the configuration of crystals put in orthogonal orientation.
Check with RP Photonics for almost any suggestions concerning tungstate lasers, together with femtosecond lasers and high-electrical power lasers.
