ABSTRACT:
A method for determining the frequency shift in a laser system by transmitting an outgoing laser beam, receiving an incoming laser beam having a frequency shift, acquiring a first signal by transmitting a portion of the incoming laser beam to an energy monitor detector and a second signal by transmitting a portion of the incoming laser beam through an "edge" filter to an edge detector, deriving a first normalized signal which is proportional to the transmission of the "edge" filter at the frequency of the incoming laser beam, deriving a second normalized signal which is proportional to the transmission of the "edge" filter at the frequency of the outgoing laser beam, and determining the frequency shift by processing the first and second normalized signals.
