We applied a transmission grating (TG) like a dispersive ingredient in our stretcher and compressor. A compact configuration was adopted, wherever the stretcher and the compressor shared one particular grating similar to that in Ref.
In conclusion, we demonstrated that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are economical nonlinear products for broadband SC era inside the near-infrared and short-wave infrared spectral ranges, when pumped by a hundred and eighty fs elementary harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO developed two octave-spanning SC spectra, which Look at to SC spectra manufactured in YAG. These resources show pretty identical performances to YAG also when it comes to threshold and ideal pump pulse energies for SC era. Nonetheless, for what problems the possibility to work at high laser pulse repetition level, YSO, LSO and LYSO clearly show strong operation only at ten kHz and quickly degrade (within just a few minutes) at twenty kHz. Besides the fairly very low SC technology threshold (169 nJ), GGG demonstrated excellent general performance traits inside the small-wave infrared Using the ideal pump pulse Electricity of 464 nJ, which is two occasions reduce than in YAG: the largest red-shifted spectral broadening and the highest spectral Electrical power density, outperforming KGW and YAG crystals in that aspect.
], but it would add considerably more cost to this component. The intra-cavity spectral obtain curve might be modulated by inserting an etalon that decreases the actual obtain with the wavelength with the utmost achieve factor[
Potassium was found out and 1st isolated by Sir Humphrey Davy in 1807. Potassium is definitely the seventh most abundant factor in the world. It can be One of the more reactive and electropositive of all metals and swiftly oxidizes. As with other alkali metals, potassium decomposes in water Using the evolution of hydrogen on account of its reacts violently with drinking water, it only takes place in mother nature in ionic salts.
The other was placed with its Np -axis parallel with the s-polarized route. A comparison was made amongst a configuration While using the crystals placed in a similar orientation (
Lastly, we investigated the lengthy-phrase performances of SC generation in crystal samples less than optimal pumping problems at larger laser repetition charges. In doing this, the crystal samples weren't translated and stored in a stationary place with regard to your pump beam in the course of the complete measurement. The illustrations illustrating sturdy very long-phrase performances of SC technology in KGW and YAG crystals at substantial laser repetition prices could be located elsewhere. Far more especially, steady functionality of KGW crystal at two MHz pulse repetition amount under pretty comparable pump beam concentrating geometry was reported recently30, While YAG crystal demonstrated stable effectiveness for a number of hrs at 200 kHz pulse repetition fee Despite incredibly limited concentrating in the pump beam (NA=0.085)32. The prolonged-expression general performance checks in LSO, LYSO and YSO discovered gradual narrowing with the SC spectra over the extensive-wavelength facet that transpired right after a certain publicity time and could be attributed on the optical degradation of those resources. By way of example, in LSO, the onset of spectral narrowing was here noticed soon after (sim 20) minutes in a laser repetition fee of ten kHz, whilst at a laser repetition level of twenty kHz, stable SC technology functionality was observed just for roughly 2 min.
Thermal results are noticeably more compact in KGW. This together with the large destruction threshold make the crystal an outstanding candidate for energy scaling. Comparing Ba(NO3)two and KGW for Raman software Ba(NO3)two are more effective in case of ns pulses and KGW �?in case of ps pulses.
The 2-pump laser could offer you around a hundred and twenty W electricity. Roughly sixty% of the maximum pump electric power was applied within our experiment considering the minimal performance on the dichroic mirrors. Less than this twin-crystal configuration, our cavity supports a 100 W pump electricity enter, as talked over in Segment 2.2. Substantial-high-quality dichroic mirrors will probably be used Later on, and laser pulses are going to be stretched to a longer pulse duration.

Determine eight Intra-cavity pulse amplification process monitored by an oscilloscope. The pulse underwent an unsaturated amplification because of the mirror damage limitation.
An example of this sort of behaviour is demonstrated in Fig. 7a. The character of spectral variations is highlighted in Fig. 7d, which shows how the SC spectrum within the long-wavelength side shrinks considerably, from 1800 nm to 1450 nm, just right after 8 minutes of exposure time in a stationary sample. LT crystal shown somewhat better extensive-time period general performance: at pulse repetition fees of as many as one hundred kHz no narrowing on either aspect in the SC spectrum was detected. Even so, speedy narrowing from the SC spectrum in LT crystal was noticed soon after the very first five minutes of operation when the heart beat repetition rate was established at 200 kHz (facts not proven). In distinction to the above mentioned supplies, BGO and GGG shown superb SC era performances without any spectral alterations in a pulse repetition price of two hundred kHz, as attested by the point series of SC spectra in BGO and GGG, revealed in Fig. 7b and c, respectively. Figure 7e and f outline equivalent shapes of SC spectra originally and at the end of 1 hour-lasting measurement in both equally supplies.
