Former perform showed that the dual-crystal configuration can be utilized to compensate to the thermal lensing impact[
Whilst ytterbium-doped laser obtain media normally show a little quantum defect, ytterbium-doped tungstates make it possible for for significantly modest values. By way of example, a 1030-nm Yb:YAG laser would Commonly be pumped close to 940 nm, While Yb:KGW or Yb:KYW may be most efficiently pumped about 981 nm.
For some applications, tungstates offer a mix of numerous practical Attributes. In particular for passive method locking, ytterbium-doped double tungstates are sometimes outstanding to other media with regard to The mixture of significant attain bandwidth, significant cross-sections, and comparatively superior thermal Attributes �?Although in Every particular self-control improved elements might be found.
The main two peaks may be related to luminescence of pure material59, while the remaining peaks can be attributed to your luminescence of unknown dopants, Even though the provider specified the sample as undoped. The luminescence of YAG crystal makes robust UV luminescence with a most intensity at 300 nm, that is attributed to mixed self-trapped exciton and antisite defect-relevant emissions60. Last but not least, no luminescence from the UV, noticeable and close to-IR was noticed in KGW and LT crystals, at the least in the detection variety of fiber spectrometer (two hundred�?00 nm).
Its pump laser demands a brief pulse duration, a reduced time jitter, and smooth temporal and spatial distributions due to the intrinsic instantaneous method. Therefore, the OPCPA process is a lot more sophisticated and expensive.
]. Etalon insertion would cause more loss, on the other hand, time-to-time optimization would introduce the potential risk of part harm and instability for the system. A nonlinear regenerative amplifier could right deliver pulses having a duration as low as ninety seven fs and a spectral bandwidth of 19 nm[
To be a Element of GDPR coverage, we use cookies to make certain we provde the most effective working experience on our website.
Comparison of spectral Vitality densities of supercontinua generated during the circumstances of optimum pumping in the investigated resources.
Consequently, with an additional improvement in our regenerative amplifier, here two mJ compressed pulses can be predicted, with no detrimental any element inside our compressor.
The threshold energy for SC era (hbox E _ textrm th ) was described because the pump pulse energy, where the blue-shifted spectral broadening speedily settles to a certain Slash-off wavelength That is still Nearly frequent Despite having even more boost in the pump pulse Electricity. The ideal Electrical power (hbox E _textrm opt ), was defined given that the pump pulse Vitality, which produces the biggest purple-shifted spectral broadening ahead of the onset of periodic modulation within the SC spectrum as a consequence of filament refocusing.

KGW has a robust Raman spectrum that extends from the ultraviolet to your close to infrared, making it valuable for A variety of programs. The crystal may be used for a reference material for Raman spectroscopy, as well as a sample for finding out Raman scattering from the strong point out.
