We applied a transmission grating (TG) as a dispersive part inside our stretcher and compressor. A compact configuration was adopted, where the stretcher as well as compressor shared 1 grating comparable to that in Ref.
In addition to its use like a Raman crystal, KGW is likewise Employed in other optical programs, for instance in laser techniques and being a scintillator in healthcare imaging.

Amplified pulses having an Electricity higher than two.five mJ is often predicted by making use of a greater pump electricity towards the regenerative amplifier and making it perform in the saturation stage. The laser fluence of ~one J/cm2 on the dichroic mirrors is considered to be down below the damage threshold of large-high-quality dielectric-coated mirrors.
The other was placed with its Np -axis parallel While using the s-polarized course. A comparison was made between a configuration While using the crystals positioned in precisely the same orientation (
Comparison of spectral Power densities of supercontinua made inside the situations of exceptional pumping while in check here the investigated elements.
Even though BGO and LT generated the narrowest SC spectra (somewhat a lot less than 1.5 optical octaves), they may be viewed as quite attractive nonlinear supplies for broadband SC era with pumping at for a longer period laser wavelengths. Owing to its big nonlinearity, BGO exhibited the bottom SC technology threshold (seventy eight nJ) among the investigated resources, which happens to be twenty five % reduce than in KGW and will be regarded as excellent nonlinear materials for quite very low-threshold SC technology. The observed stable and durable harm-absolutely free performance of BGO and GGG at 200 kHz pulse repetition charge indicates that these nonlinear resources have a possible for SC era at even better, MHz, repetition premiums. What's more, these products provide SC radiation with a great set of parameters that are important for apps in significant pace spectroscopy and imaging that use bulk-produced SC, see e.g.17,18,19,20.

A multi-pass major amplifier will even more Enhance the Electrical power to previously mentioned 40 mJ. We're going to use cryogenically cooled Yb:KGW technological innovation to restrain the thermal impact. Two stages of compression will be utilized following amplification. The primary stage consists of a standard Treacy-kind compressor, and will compress the heartbeat length to down below three hundred fs using an efficiency of somewhere around 70%. The 2nd phase will involve a fuel-crammed multi-pass cell[
The scattered photons have a different wavelength and Electrical power compared to incident photons, which generates a Raman spectrum.
KGW crystals are made use of as Raman scattering components because they have sturdy Raman scattering in a quantity of various wavelengths. Any time a laser beam is directed onto the crystal, the photons from the laser beam interact with the crystal lattice, causing several of the photons to scatter in another path.
