Down the road, an investigation about the spectral attain curve of Yb:KGW in the most crucial amplifier might be performed under cryogenic temperature evolution from 77 K to three hundred K. The Doing work temperature will be controlled to realize broader gain bandwidth and less change within the central wavelength of the leading amplifier.
The purple-shifted part of the SC is of sensible great importance, especially for what concerns the overall performance of broadly tunable optical parametric amplifiers pumped by the fundamental harmonics of Yb lasers. The dearth of seed photons in the long-wavelength location from the SC spectrum boundaries the amplification efficiency and ends in pulse-to-pulse energy fluctuations within the degeneracy location on the optical parametric amplifier. This part is quantified in Fig. 6a by plotting the SC spectra when it comes to spectral Strength density, which was believed by measuring the Electrical power from the axial part of SC radiation (that's the sole nearly valuable Element of SC emission). KGW crystal produces the very best spectral Electricity density from the 1200�?450 nm selection, as famous inside of a modern study30.
Its pump laser desires a short pulse duration, a reduced time jitter, and easy temporal and spatial distributions because of the intrinsic instantaneous procedure. Hence, the OPCPA method is a lot more intricate and high priced.
Just before the development of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser achieve medium. It had been actually used in the very first continuously functioning crystal laser.
On the other hand, after Nd3+:YAG became commercially obtainable, click here the interest in CaWO4 dropped sharply. In later on a long time, certain other tungstate crystals began to attract many interest.
The put together gain is sophisticated and may be measured less than various pumping conditions because of the quasi-a few-amount method conduct in the Yb-doped get medium. The blueshift, with 1 peak from 1037 nm under the same crystal placement orientation to 1035 nm underneath the orthogonal crystal placement orientation, could consequence within the reabsorption losses at a protracted wavelength in the crystal where the laser polarization is parallel to its Nm -axis, creating the gain at 1035 nm better than that at 1037 nm beneath orthogonal orientation.
Ask RP Photonics for any assistance regarding tungstate lasers, which includes femtosecond lasers and large-electrical power lasers.
The 2-pump laser could offer you approximately 120 W energy. Approximately sixty% of the utmost pump energy was used in our experiment contemplating the small general performance on the dichroic mirrors. Under this dual-crystal configuration, our cavity supports a a hundred W pump ability input, as talked over in Segment two.2. Superior-high quality dichroic mirrors will likely be utilized Down the road, and laser pulses will be stretched to an extended pulse duration.

A multi-pass principal amplifier will more boost the Electrical power to previously mentioned 40 mJ. We are going to apply cryogenically cooled Yb:KGW engineering to restrain the thermal effect. Two phases of compression will probably be applied following amplification. The main stage requires a typical Treacy-style compressor, and will compress the pulse duration to beneath 300 fs using an performance of around 70%. The 2nd stage consists of a gasoline-crammed multi-pass cell[
Figure four Beam radius variation on The 2 crystals though altering the focal duration of the thermal lensing effect.
The origin of the aspect's name emanates from the English phrase 'potash,' that means pot ashes, and the Arabic phrase qali
