A not-for-profit Group, IEEE is the planet's greatest technical Expert organization committed to advancing technological know-how for the advantage of humanity.
Together with its use as a Raman crystal, KGW is additionally Utilized in other optical apps, which include in laser units and for a scintillator in medical imaging.
The monoclinic crystal constructions leads to a pure birefringence, assisting to prevent thermally induced polarization rotation and depolarization reduction.
Amplified pulses with the Vitality previously mentioned 2.5 mJ might be predicted by making use of an increased pump power to the regenerative amplifier and rendering it do the job for the saturation stage. The laser fluence of ~1 J/cm2 around the dichroic mirrors is believed to generally be underneath the injury threshold of superior-high quality dielectric-coated mirrors.
Several solutions are adopted to resolve this problem. An acousto-optical programmable dispersive filter is often utilized to modulate the seed’s spectrum to suppress the get-narrowing result[
The black line denotes the configuration Together with the crystals placed in a similar orientation, whilst the purple line is under the configuration of crystals placed in orthogonal get more info orientation.
Check with RP Photonics for just about any suggestions regarding tungstate lasers, like femtosecond lasers and substantial-electrical power lasers.
First off, For the reason that filament-induced luminescence originates from simultaneous absorption of several photons, whose overall Power exceeds the bandgap Electrical power of material, it offers uncomplicated separation of excitation and emission wavelengths and presents extremely sturdy signal Even with being emitted more than your entire stable angle. The position of the filament track inside the crystal may be easily altered in a wished-for way by different the pump pulse Vitality, Whilst the depth clamping in a lightweight filament drastically decreases the chance of optical harm. These options could be beneficial for getting supplemental details about crystal homogeneity and expose the existence and distribution of different dopants within the sample.

-switched laser output underneath the two crystal placement configurations. The black line denotes the configuration Along with the crystals positioned in the identical orientation, whilst the pink line is beneath the configuration of crystals put in orthogonal orientation.
