]. Due to the quick storage time, Ti:sapphire is typically pumped by frequency-doubled Nd:YAG or Nd:glass stable-point out lasers, which results in a bulky and complicated technique with high Price tag. When compared with regular CPA laser devices, the OPCPA method can attain a shorter pulse duration and the next peak electricity.
Making use of our advertising and marketing package deal, you could Show your brand, even further below your product description, and these will been witnessed by lots of photonics industry experts.
A not-for-financial gain Corporation, IEEE is the world's major technological Specialist organization committed to advancing technology for the benefit of humanity.
In summary, we shown that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are productive nonlinear materials for broadband SC generation while in the near-infrared and small-wave infrared spectral ranges, when pumped by a hundred and eighty fs basic harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO produced two octave-spanning SC spectra, which Review to SC spectra made in YAG. These supplies exhibit pretty comparable performances to YAG also with regards to threshold and best pump pulse energies for SC technology. On the other hand, for what problems the chance to work at large laser pulse repetition charge, YSO, LSO and LYSO demonstrate resilient operation only at 10 kHz and swiftly degrade (within a couple of minutes) at 20 kHz. Moreover the somewhat minimal SC era threshold (169 nJ), GGG demonstrated exceptional functionality attributes during the brief-wave infrared Using the optimal pump pulse Vitality of 464 nJ, which is two situations lower than in YAG: the most important purple-shifted spectral broadening and the best spectral Electrical power density, outperforming KGW and YAG crystals in that component.
Its pump laser requires a short pulse duration, a very low time jitter, and clean temporal and spatial distributions as a result of intrinsic instantaneous process. So, the OPCPA technique is much more challenging and high priced.
For tungstates, the ytterbium doping focus can be very high without significant quenching since the changed ions have an incredibly identical ion radius, as well as the inter-ion length is relatively large.
One other was put with its Np -axis parallel with the s-polarized route. A comparison was manufactured in between a configuration With all the crystals positioned in the identical orientation (
The black line denotes the configuration with the crystals positioned in exactly the same orientation, when the crimson line is underneath click here the configuration of crystals put in orthogonal orientation.
]. This process was determined by The truth that the spectral emission cross-portion curves vary from one another when laser polarization is paralleled to the different optical axis of Yb-doped double tungstates[
The two-pump laser could present approximately one hundred twenty W power. Roughly sixty% of the utmost pump electrical power was used inside our experiment contemplating the very low performance in the dichroic mirrors. Under this dual-crystal configuration, our cavity supports a 100 W pump electricity input, as discussed in Area 2.two. Higher-good quality dichroic mirrors is going to be made use of in the future, and laser pulses are going to be stretched to an extended pulse period.
The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The input with the stretcher (incident angle: 52°) Which on the compressor incident on the grating were being through the same side; consequently, a slight angular tuning with the grating may very well be created to obtain the most effective compression end result. From the compressor, the input angle over the grating and the distance involving the interpretation phase (S1) as well as transmission grating (TG) were being intended to compensate for your stretcher dispersion and all dispersion launched by the components.
-switched output spectrum in the regenerative amplifier supports a sub-160 fs pulse amplification. Hence, pulses with energies of around two mJ and period down below two hundred fs could be obtained applying higher-excellent dichroic mirrors along with a broader-spectrum laser seed. This regenerative amplifier will work as a very good pre-amplifier for further laser amplification.
Figure eight Intra-cavity pulse amplification method monitored by an oscilloscope. The heart beat underwent an unsaturated amplification due to the mirror damage limitation.
