We utilised a transmission grating (TG) as a dispersive part within our stretcher and compressor. A compact configuration was adopted, in which the stretcher along with the compressor shared a single grating similar to that in Ref.
Therefore There exists small liberty for optimizing the dispersion compensation influence. Sub-two hundred fs pulses may be predicted with a broader bandwidth seed input. Because of the twin-crystal configuration, the laser cavity provides a near diffraction restricted laser beam with M
], but it will include much more Value to this element. The intra-cavity spectral obtain curve might be modulated by inserting an etalon that lowers the actual achieve at the wavelength with the utmost get variable[
For tungstates, the ytterbium doping concentration can be very high without the need of major quenching since the replaced ions have an exceptionally very similar ion radius, as well as the inter-ion length is fairly substantial.
SEMI EL challenge is a worldwide provider of supplies, products, spare components and provides for the semiconductor sector.
Comparison of spectral Power densities of supercontinua created during the problems of optimal pumping inside the investigated products.
Even though BGO and LT generated the narrowest SC spectra (slightly under one.five optical octaves), they may be considered as quite attractive nonlinear supplies for broadband SC generation with pumping at extended laser wavelengths. Owing to its significant nonlinearity, BGO exhibited the lowest SC generation threshold (seventy eight nJ) Amongst the investigated elements, that's 25 % decreased than in KGW and could be regarded as outstanding nonlinear materials for really reduced-threshold SC technology. The noticed secure and sturdy problems-cost-free efficiency of BGO and GGG at two hundred kHz pulse repetition fee suggests that these nonlinear supplies have a possible for SC era at even better, MHz, repetition prices. Moreover, these components present SC radiation with an excellent list of parameters that happen to be important for apps in higher pace spectroscopy and imaging that hire bulk-generated SC, see e.g.seventeen,18,19,twenty.
The purple-shifted Element of the SC spectrum in BGO has the lowest spectral Electrical power density, that is 1–2 orders of magnitude decreased than in here the remainder of the components. Having said that, pretty lower Strength threshold of SC generation, as well as low best pump Vitality in BGO, must be pointed out. The approximated spectral Electrical power densities generated in LSO and LYSO are really just like YAG through the entire significant Element of the SC spectrum. Quite possibly the most exciting discovering in that regard is GGG crystal, which, Irrespective of pretty moderate blue-shifted spectral broadening, produces the biggest spectral crimson-change and the best spectral Power density inside the 1600�?000 nm array, which is nearly an buy of magnitude larger than that developed in YAG.

-switched output spectrum in the regenerative amplifier supports a sub-one hundred sixty fs pulse amplification. Thus, pulses with energies of nearly two mJ and period underneath 200 fs is often attained employing greater-high-quality dichroic mirrors along with a broader-spectrum laser seed. This regenerative amplifier will work as a great pre-amplifier for even more laser amplification.
