Utilizing our promoting bundle, you can Screen your brand, even more under your product or service description, and these will been viewed by lots of photonics gurus.
The attain bandwidth e.g. of Yb:KGW and Yb:KYW is rather huge when compared with that of Yb:YAG. This allows for huge wavelength tunability and for Significantly shorter pulse durations from manner-locked lasers. Values perfectly down below 100 fs are actually realized with passive method locking.
The pink-shifted A part of the SC is of simple great importance, especially for what issues the overall performance of broadly tunable optical parametric amplifiers pumped by the elemental harmonics of Yb lasers. The shortage of seed photons from the prolonged-wavelength region of the SC spectrum boundaries the amplification performance and brings about pulse-to-pulse energy fluctuations throughout the degeneracy location from the optical parametric amplifier. This factor is quantified in Fig. 6a by plotting the SC spectra with regards to spectral Electricity density, which was believed by measuring the Power of your axial Portion of SC radiation (which is the sole practically helpful Portion of SC emission). KGW crystal provides the very best spectral Electricity density while in the 1200�?450 nm array, as pointed out within a current study30.
The monoclinic crystal structures ends in a natural birefringence, helping to stay clear of thermally induced polarization rotation and depolarization loss.
The comparison with glasses is acceptable since the huge attain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
Quite a few methods happen to be adopted to solve this problem. An acousto-optical programmable dispersive filter can be utilized to modulate the seed’s spectrum to suppress the obtain-narrowing influence[

The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The enter of the stretcher (incident angle: 52°) Which from the compressor incident in the grating had been in the exact same aspect; hence, a slight angular tuning of the grating might be created to obtain the best compression final result. From the compressor, the enter angle over the grating and the gap concerning the translation stage (S1) as well as transmission grating (TG) were being made to compensate to the stretcher dispersion and all dispersion released from the elements.
KGW has a solid Raman spectrum that extends from your ultraviolet into the in close proximity to infrared, making it practical for An array of programs. The crystal may be used like a reference materials for Raman spectroscopy, as well as a sample for studying Raman scattering within the good state.
