In pulsed laser systems, flashlamps are often simmered during the period of time between the main discharge pulses. Simmering is nothing more than allowing a trickle current (50mA to 10A) to flow in the lamp between pulses. Flashlamp simmering is beneficial for two reasons. First, having an established conduction path in the flashlamp at the time of the main discharge pulse results in less variation in shot to shot pulse energy. Second, because arc expansion during the pulse is less violent, lamp lifetimes are improved in simmered systems. In general, both stability and lamp lifetime improve with increasing simmer current.

AMI’s simmer supplies are powered from a 24VDC source and provide both a built-in automatic ignition restrike circuit and a post-flash boost mechanism. These features minimize the possibility of missing pulses when operating with a continuous train of laser pulses.
