For a few purposes, tungstates supply a mix of various valuable properties. Particularly for passive manner locking, ytterbium-doped double tungstates are frequently superior to other media regarding the combination of higher acquire bandwidth, large cross-sections, and relatively good thermal Qualities �?Although in Each and every certain self-control much better elements might be identified.
In summary, we shown that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are effective nonlinear elements for broadband SC generation from the close to-infrared and small-wave infrared spectral ranges, when pumped by one hundred eighty fs essential harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO made two octave-spanning SC spectra, which Assess to SC spectra produced in YAG. These components show pretty similar performances to YAG also with regard to threshold and optimum pump pulse energies for SC era. On the other hand, for what issues the likelihood to function at significant laser pulse repetition rate, YSO, LSO and LYSO display long lasting Procedure only at 10 kHz and immediately degrade (inside a few minutes) at twenty kHz. Besides the somewhat small SC generation threshold (169 nJ), GGG demonstrated outstanding performance traits inside the brief-wave infrared Together with the best pump pulse Strength of 464 nJ, that's two instances reduced than in YAG: the largest pink-shifted spectral broadening and the best spectral Power density, outperforming KGW and YAG crystals in that element.
In contrast, the seed laser may be amplified to more than one mJ under the orthogonal orientation configuration.
Prior to the development of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser get medium. It was the truth is used in the very first constantly running crystal laser.
Later on, We'll undertake a laser seed with a broader spectral bandwidth and apply an acousto-optical programmable dispersive filter to modulate the seed’s spectrum to produce total use in the obtain bandwidth of our regenerative amplifier.
KGW (potassium gadolinium tungstate) is really a crystal that is commonly used as being a Raman crystal in Raman spectroscopy. It is a colorless, transparent crystal that has a high Raman scattering effectiveness and a robust Raman spectrum, making it appropriate for A variety of Raman programs.
We strategy to spice up the heartbeat Electricity to earlier mentioned forty mJ in two-phase multi-move amplifiers, comparable to a achieve issue of 20. In Just about every amplifier, we will even undertake two cascaded crystals positioned beneath orthogonal orientation to reduce the thermal load on each crystal and compensate with the attain-narrowing influence.
We formulated a diode-pumped Yb:KGW regenerative amplifier because the front finish of the kilohertz terawatt laser system. Wide bandwidth pulses ended up received by implementing twin crystals with distinctive orientations in their optical axes[

KGW has a strong Raman spectrum that extends within the ultraviolet to the close to infrared, rendering it practical for A variety of apps. The crystal may be used like a reference product for Raman spectroscopy, in addition to a sample for researching Raman scattering inside the reliable point out.
