We employed a transmission grating (TG) like a dispersive element in our stretcher and compressor. A compact configuration was adopted, where the stretcher and the compressor shared a person grating just like that in Ref.
Thus You can find small flexibility for optimizing the dispersion compensation impact. Sub-200 fs pulses is usually expected using a broader bandwidth seed enter. Thanks to the dual-crystal configuration, the laser cavity delivers a around diffraction confined laser beam with M
], but it will incorporate much more Value to this part. The intra-cavity spectral attain curve could possibly be modulated by inserting an etalon that lessens the actual obtain in the wavelength with the most get factor[
Amplified pulses using an Vitality over two.5 mJ is usually anticipated by implementing a greater pump ability for the regenerative amplifier and rendering it work in the saturation level. The laser fluence of ~1 J/cm2 to the dichroic mirrors is considered to get down below the destruction threshold of higher-high-quality dielectric-coated mirrors.

KGW (potassium gadolinium tungstate) is usually a crystal that is usually employed like a Raman crystal in Raman spectroscopy. It's really a colorless, transparent crystal that features a here high Raman scattering effectiveness and a robust Raman spectrum, rendering it suitable for A variety of Raman programs.
Request RP Photonics for virtually any information about tungstate lasers, including femtosecond lasers and higher-energy lasers.

A multi-move principal amplifier will even more boost the Electricity to previously mentioned forty mJ. We're going to apply cryogenically cooled Yb:KGW engineering to restrain the thermal influence. Two phases of compression will be utilized following amplification. The initial phase entails a common Treacy-form compressor, and could compress the heart beat length to underneath three hundred fs having an effectiveness of somewhere around 70%. The second stage consists of a gasoline-stuffed multi-move mobile[

Equally energies are marked because of the dashed strains and their values are labeled in the plots. The similar characteristics were being also observed in KGW and YAG crystals, whose spectral broadening dynamics are demonstrated for just a comparison in Fig. 4.
