Previous perform showed that the dual-crystal configuration may be used to compensate for your thermal lensing effect[
Whilst ytterbium-doped laser achieve media typically show a little quantum defect, ytterbium-doped tungstates let for specially tiny values. For instance, a 1030-nm Yb:YAG laser would normally be pumped close to 940 nm, Whilst Yb:KGW or Yb:KYW could possibly be most efficiently pumped close to 981 nm.

In its elemental kind, potassium has a silvery gray metallic overall look, but its compounds (like potassium hydroxide) are more regularly Utilized in industrial and chemical programs.
The monoclinic crystal structures brings about a organic birefringence, assisting to avoid thermally induced polarization rotation and depolarization decline.
Just before the event of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser gain medium. It absolutely was in actual fact Utilized in the first consistently functioning crystal laser.
Nevertheless, as soon as Nd3+:YAG became commercially obtainable, the desire in CaWO4 dropped sharply. In later yrs, particular other tungstate crystals began to catch the attention of plenty of awareness.
KGW (potassium gadolinium tungstate) is a crystal that is commonly employed being a Raman crystal in Raman spectroscopy. It's really a colorless, clear crystal that includes a high Raman scattering effectiveness and a robust Raman spectrum, which makes it suitable for a range of Raman applications.
We system to boost the pulse energy to earlier mentioned 40 mJ in two-stage multi-move amplifiers, equivalent to a achieve component of twenty. In Every amplifier, we will likely undertake two cascaded crystals put less than orthogonal orientation to lessen the thermal load on Each individual crystal and compensate to the achieve-narrowing result.

The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The enter of the stretcher (incident angle: 52°) Which with the compressor incident with the grating had been from your exact same aspect; consequently, a slight angular tuning with the grating might be designed to obtain the ideal compression result. While in the compressor, the input angle within the grating and the gap involving the interpretation phase read more (S1) along with the transmission grating (TG) were being made to compensate for your stretcher dispersion and all dispersion introduced from the components.
A multi-pass key amplifier will more Enhance the energy to previously mentioned 40 mJ. We'll use cryogenically cooled Yb:KGW technologies to restrain the thermal result. Two levels of compression will likely be employed just after amplification. The primary phase will involve a common Treacy-sort compressor, and could compress the heart beat duration to under three hundred fs with the effectiveness of close to 70%. The second stage requires a fuel-loaded multi-go cell[
The scattered photons have a different wavelength and Electricity as opposed to incident photons, which creates a Raman spectrum.
The two energies are marked through the dashed strains as well as their values are labeled while in the plots. The equivalent capabilities had been also noticed in KGW and YAG crystals, whose spectral broadening dynamics are shown for the comparison in Fig. four.
