Previous perform confirmed that the dual-crystal configuration can be employed to compensate for that thermal lensing influence[

We made use of a transmission grating (TG) to be a dispersive element in our stretcher and compressor. A compact configuration was adopted, in which the stretcher as well as the compressor shared just one grating similar to that in Ref.
Hence There exists tiny independence for optimizing the dispersion compensation impact. Sub-200 fs pulses is usually expected having a broader bandwidth seed input. Due to the twin-crystal configuration, the laser cavity delivers a in close proximity to diffraction minimal laser beam with M
The datasets utilised and/or analysed throughout The present research available with the corresponding creator on fair ask for.
Prior to the development of Nd:YAG, Nd3+:CaWO4 was an important unusual-earth-doped laser achieve medium. It absolutely was in reality used in the initial repeatedly operating crystal laser.
The other was positioned with its Np -axis parallel Along with the s-polarized direction. A comparison was manufactured amongst a configuration While using the crystals put in precisely the same orientation (
Comparison of spectral Power densities of supercontinua developed within the ailments of optimal pumping while in the investigated materials.
]. This method was based upon The point that the spectral emission cross-area curves vary from one another when laser polarization is paralleled to the different optical axis of Yb-doped double click here tungstates[
Determine four Beam radius variation on the two crystals although switching the focal duration of your thermal lensing outcome.
Even though BGO, GGG, YSO, LSO and LYSO often serve as laser hosts37, they are principally recognized as economical scintillators, whose scintillation Homes are studied very well38. Nevertheless, the nonlinear optical Houses of such crystals and so their prospective to function nonlinear materials for SC era especially, and every other experiments relating to nonlinear propagation of rigorous femtosecond laser pulses, remain quite improperly studied. Thus far, GGG, LT23,twenty five and YSO24 were only sketchily tested for SC era with Ti:sapphire laser pumping, having said that, to the very best of our expertise, Not one of the investigated products ended up examined with Yb-laser pumping, specifically for what issues their functionality at incredibly high (tens to many hundreds of kHz) pulse repetition rates.
-switched laser output beneath the two crystal placement configurations. The black line denotes the configuration With all the crystals put in the same orientation, while the red line is underneath the configuration of crystals put in orthogonal orientation.
Determine 4 Beam radius variation on The 2 crystals while shifting the focal duration with the thermal lensing impact.
Assembling tungsten oxide hydrate nanocrystal colloids fashioned by laser ablation in liquid into fast-reaction electrochromic movies.
