By adjusting the plate positions with careful consideration of the thermal lensing effect due to the high average power, we compressed the output pulse with a 184-fs initial duration to 5.7 fs by using only group-delay-dispersion compensation. This pulse achieved a sufficient beam quality ($M^2$ < 1.5) reaching a focused intensity over 10$^{14}$ W/cm$^2$ and a high spatial-spectral homogeneity (98%).
