Down the road, an investigation on the spectral attain curve of Yb:KGW in the most crucial amplifier are going to be done beneath cryogenic temperature evolution from seventy seven K to three hundred K. The Functioning temperature will probably be managed to realize broader attain bandwidth and fewer change in the central wavelength of the main amplifier.
Hence There is certainly very little freedom for optimizing the dispersion payment outcome. Sub-200 fs pulses can be predicted by using a broader bandwidth seed input. Due to the dual-crystal configuration, the laser cavity provides a near diffraction restricted laser beam with M
If This can be The 1st time you made use of this element, you're going to be requested to authorise Cambridge Main to connect together with your Dropbox account. Discover more details on conserving articles to Dropbox.
Right before the event of Nd:YAG, Nd3+:CaWO4 was an important exceptional-earth-doped laser gain medium. It had been in fact used in the very first constantly operating crystal laser.
Later on, We'll adopt a laser seed having a broader spectral bandwidth and utilize an acousto-optical programmable dispersive filter to modulate the seed’s spectrum to make total use of the get bandwidth of our regenerative amplifier.
Comparison of spectral Electrical power densities of supercontinua generated in the circumstances of optimum pumping within the investigated elements.
The actual spectra ended up reconstructed by correcting the measured spectra by having an account for the filter transmission functions and get more info with the sensitivity functions on the spectrometers at the information publish-processing phase. The spectral dynamics in Each individual sample was measured by high-quality tuning the pump pulse Strength with a pc-managed attenuator which was integrated within the laser process. Thermal Power meter EM (Ophir 3A-PF-12) was accustomed to measure the SC Electrical power which was thereafter used to determine the spectral Strength density with the SC radiation. The many measurements have been done without any translation with the sample with respect into the pump beam.
The 2-pump laser could give around one hundred twenty W electricity. Around 60% of the maximum pump ability was utilized within our experiment considering the low performance in the dichroic mirrors. Beneath this twin-crystal configuration, our cavity supports a one hundred W pump power input, as reviewed in Part two.2. Large-good quality dichroic mirrors might be utilised Down the road, and laser pulses is going to be stretched to a longer pulse period.

KGW has a solid Raman spectrum that extends from the ultraviolet into the close to infrared, which makes it handy for A variety of purposes. The crystal can be employed like a reference materials for Raman spectroscopy, in addition to a sample for studying Raman scattering from the strong state.

The origin on the aspect's title arises from the English phrase 'potash,' that means pot ashes, and the Arabic phrase qali
