Later on, an investigation about the spectral obtain curve of Yb:KGW in the principle amplifier is going to be executed under cryogenic temperature evolution from 77 K to three hundred K. The Doing work temperature might be managed to comprehend broader achieve bandwidth and less change for the central wavelength of the leading amplifier.
Determine 7 exhibits the calculated dispersion compensation result. The compressed pulse period is about 185 fs if the duration of input pulses is one hundred fifty fs. The discrepancy concerning them is going to be drastically decreased with an extended pulse input mainly because uncompensated large-buy dispersion issues less for for a longer period pulses. This configuration was used to exhibit the compressibility of our amplified pulses for the preliminary phase of our complete procedure. Later on we might undertake a grating-pair compressor for fine payment for top-buy dispersion.
-switched mode. The bandwidth inside the orthogonal orientation was Obviously A lot broader. The calculated Fourier remodel limited pulse duration was as limited as sub-a hundred and sixty fs. Underneath the configuration where The 2 crystals were being put in precisely the same orientation, Along with the seed input, the amplified pulse bandwidth was only 3 nm with 180 μJ Power when it broke the dichroic mirrors.
Right before the event of Nd:YAG, Nd3+:CaWO4 was a very important rare-earth-doped laser get medium. It was in actual fact used in KGW Crystal the main continually operating crystal laser.

KGW (potassium gadolinium tungstate) is really a crystal that is commonly employed like a Raman crystal in Raman spectroscopy. This is a colorless, transparent crystal that includes a substantial Raman scattering efficiency and a solid Raman spectrum, making it suited to A selection of Raman applications.
]. This technique was depending on the fact that the spectral emission cross-part curves differ from each other when laser polarization is paralleled to the different optical axis of Yb-doped double tungstates[

Even though BGO, GGG, YSO, LSO and LYSO occasionally serve as laser hosts37, They are really largely discovered as productive scintillators, whose scintillation Homes are examined fairly well38. On the other hand, the nonlinear optical properties of these crystals and so their prospective to function nonlinear components for SC era in particular, and some other experiments concerning nonlinear propagation of powerful femtosecond laser pulses, remain really badly researched. So far, GGG, LT23,twenty five and YSO24 were being only sketchily analyzed for SC era with Ti:sapphire laser pumping, having said that, to the best of our understanding, none of the investigated materials were being examined with Yb-laser pumping, specifically for what considerations their efficiency at quite substantial (tens to countless kHz) pulse repetition costs.
Tungstates tend to acquire high Raman coefficients (�?Raman scattering). Therefore, they will produce sizeable Raman obtain at average optical intensities. It can be done to make use of the laser crystal alone like a Raman converter.
Determine eight Intra-cavity pulse amplification course of action monitored by an oscilloscope. The heart beat underwent an unsaturated amplification due to the mirror hurt limitation.
]. The dual-crystal configuration lowers the thermal load on Every crystal though retaining a large gain, and facilitates the payment of every one’s thermal lensing outcome. Therefore, the laser cavity can do the job with a considerable steadiness array above the thermal lensing outcome variation.
