We utilised a transmission grating (TG) to be a dispersive element in our stretcher and compressor. A compact configuration was adopted, the place the stretcher plus the compressor shared just one grating similar to that in Ref.
In its elemental sort, potassium features a silvery grey metallic physical appearance, but its compounds (like potassium hydroxide) tend to be more often Employed in industrial and chemical apps.
], but it will include a lot more Expense to this element. The intra-cavity spectral acquire curve might be modulated by inserting an etalon that lowers the actual achieve at the wavelength with the most gain factor[
Amplified pulses using an Electrical power above 2.five mJ is usually predicted by implementing an increased pump electric power to the regenerative amplifier and making it perform for the saturation level. The laser fluence of ~1 J/cm2 around the dichroic mirrors is thought to generally be under the injury threshold of high-high quality dielectric-coated mirrors.

KGW (potassium gadolinium tungstate) is a crystal that is commonly made use of being a Raman crystal in Raman spectroscopy. It's a colorless, clear crystal that features a large Raman scattering efficiency and a solid Raman spectrum, making it ideal for A selection of Raman purposes.
The spectral measurements of filament-induced luminescence advise that scintillating properties of products could be readily studied utilizing femtosecond close to-infrared light resource by way of multiphoton excitation while in the filamentation routine, which makes it possible for simple separation of excitation and emission wavelengths and low chance of optical harm.
We produced a diode-pumped Yb:KGW regenerative amplifier as being the entrance end from the kilohertz terawatt laser method. Broad bandwidth pulses have been attained by implementing twin crystals with different orientations in their optical axes[
These components can be utilized for frequency conversion in lasers for extending of tuning array. SRS in crystals is appropriate with present-day all-solid-state engineering and supplies a quite more info simple, compact signifies of frequency conversion.
-switched output spectrum of your regenerative amplifier supports a sub-160 fs pulse amplification. For that reason, pulses with energies of as many as 2 mJ and period down below 200 fs may be attained working with higher-top quality dichroic mirrors and a broader-spectrum laser seed. This regenerative amplifier performs as an excellent pre-amplifier for further more laser amplification.
