The STHO series of femtosecond solid-state lasers boast excellent pulse quality. The left image shows the output pulse curve of the STHO-10W-HE series. The blue dashed line represents the Fourier Transform Limited pulse (FTL) from the spectrum on the right, indicating the optimal pulse width achievable by this laser. The black solid line is the actual measured autocorrelation curve, showing that at 1mJ energy output, the pulse width is very close to the FTL, with noise floor intensity less than 3% of the peak value, and the overall pulse intensity has a very small energy distribution beyond ±500fs.
