A 38 MHz RF clock is divided by 8 thru 4096. 2 Percentage of incident pulse energy in diffracted output pulse. 3 Main pulse to non-adjacent pulses. Main pulse to adjacent pulse is >100: 1 T eO2 cell or >200:1 SiO2 cell. Contrast ratios for high-power pumped femtosecond systems are 0.5 times the given values for the T eO2 cell. 4 For SHG operation, the fundamental output must be pulse picked first, then frequency doubled.
