What are the possible pulse lengths and duty cycles?

The pulse driver LDD100 can amplify pulses with lengths of 5ns…300ns and minimal period of 100ns. Maximal duty cycle is 50% (with reduced stability and not continuously to prevent overheating, up to 90%). The pulse generator TPG128 is capable of generating pulses with lengths of 20ns…200ns (with reduced stability down to 10ns) and period of 0.2us…10.5us. Duty cycle can vary in the range of 0.1%…80% (with reduced stability up to 95%). In combination with LDD100, only 50% duty cycle can be reached, since the power supply in TPG128 which is feeding LDD100 is not specified for higher values. Provide external power source for LDD100 if more than 50% is needed. In any case, contact Alpes Lasers SA first, if duty cycles of more than 5% are needed.
