The thermal conductivity of frequent double tungstates is with the get to three–4 W/(K m) �?which isn't undesirable when compared with other laser crystals (Whilst a number of situations a lot less than for YAG), and relatively substantial when compared While using the thermal conductivity of regular Eyeglasses.
Figure 8 Intra-cavity pulse amplification course of action monitored by an oscilloscope. The heartbeat underwent an unsaturated amplification because of the mirror harm limitation.
In conclusion, we demonstrated that undoped scintillator crystals: BGO, GGG, YSO, LSO and LYSO are effective nonlinear products for broadband SC generation while in the near-infrared and shorter-wave infrared spectral ranges, when pumped by 180 fs fundamental harmonic pulses from an amplified Yb:KGW laser. YSO, LSO and LYSO created two octave-spanning SC spectra, which Assess to SC spectra developed in YAG. These supplies show fairly comparable performances to YAG also concerning threshold and exceptional pump pulse energies for SC generation. Nevertheless, for what considerations the chance to function at higher laser pulse repetition level, YSO, LSO and LYSO show long lasting operation only at ten kHz and rapidly degrade (within just a few minutes) at twenty kHz. Aside from the fairly reduced SC generation threshold (169 nJ), GGG shown superb general performance characteristics within the quick-wave infrared With all the optimum pump pulse Electrical power of 464 nJ, and that is two times decreased than in YAG: the most important purple-shifted spectral broadening and the very best spectral Vitality density, outperforming KGW and YAG crystals in that element.
