1. A method for monitoring degradation of a flashlamp comprising:

  • triggering the flashlamp to create a plasma and produce a light pulse corresponding to the created plasma;

    obtaining a plurality of values of a first parameter as a function of time during the produced light pulse to generate a pulse waveform of the produced light pulse;

    retrieving a reference pulse waveform of a reference light pulse, the reference pulse waveform including a plurality of values of the first parameter as a function of time during the reference light pulse;

    comparing the generated pulse waveform of the produced light pulse to at least the reference pulse waveform to determine a difference therebetween; and

    flagging an end-of-lamp-life condition when the difference exceeds a predetermined threshold, wherein the flagging step comprises preventing firing of the flashlamp.
