Consequently There may be small flexibility for optimizing the dispersion payment impact. Sub-two hundred fs pulses can be expected by using a broader bandwidth seed enter. Due to the dual-crystal configuration, the laser cavity delivers a in close proximity to diffraction restricted laser beam with M
-switched mode. The bandwidth in the orthogonal orientation was Obviously A lot broader. The calculated Fourier rework limited pulse period was as shorter as sub-one hundred sixty fs. Underneath the configuration wherever The 2 crystals had been positioned in the exact same orientation, Using the seed input, the amplified pulse bandwidth was only three nm with one hundred eighty μJ Electrical power when it broke the dichroic mirrors.
For tungstates, the ytterbium doping focus can be extremely significant with no important quenching because the replaced ions have a very identical ion radius, plus the inter-ion length is comparatively significant.

The black line denotes the configuration With all the crystals placed in precisely the same orientation, while the red line is under the configuration of crystals placed in orthogonal orientation.
We strategy to boost the heart beat Vitality to earlier mentioned forty mJ in two-stage multi-pass amplifiers, similar to a achieve component of 20. In Just about every amplifier, we will even adopt two cascaded crystals placed below orthogonal orientation to lessen the thermal load on each crystal and compensate for your attain-narrowing effect.
The purple-shifted Section of the SC spectrum in BGO has the lowest spectral Electrical power density, that's one–two orders of magnitude reduce than in the rest of the resources. Nevertheless, pretty small Power threshold of SC generation, along with reduced best pump Strength in BGO, must be identified. The approximated spectral Power densities created in LSO and LYSO are quite just like YAG all through the significant Element of the SC spectrum. The most appealing locating in that regard is GGG crystal, which, despite very reasonable blue-shifted spectral broadening, creates the most important spectral red-change and the highest spectral Strength density in the 1600�?000 nm selection, which is sort of an purchase of magnitude better check here than that produced in YAG.
Despite the fact that BGO, GGG, YSO, LSO and LYSO occasionally serve as laser hosts37, They can be generally discovered as efficient scintillators, whose scintillation Homes are studied really well38. Nonetheless, the nonlinear optical Homes of those crystals and so their probable to function nonlinear elements for SC generation especially, and almost every other experiments concerning nonlinear propagation of rigorous femtosecond laser pulses, remain extremely improperly researched. Up to now, GGG, LT23,twenty five and YSO24 were being only sketchily analyzed for SC technology with Ti:sapphire laser pumping, having said that, to the best of our expertise, Not one of the investigated supplies ended up examined with Yb-laser pumping, specifically for what worries their effectiveness at pretty significant (tens to numerous kHz) pulse repetition costs.
