Abstract

We report a novel nanosecond pulsed laser with a highly accurate gigahertz beat that is realized by injection locking to gigahertz sidebands generated from a single-frequency cw laser radiation using a Mach–Zehnder type intensity modulator. It is shown from both the spectrum of the pulsed sidebands and their coherent beat in the time domain that the frequency accuracy of an rf oscillator driving the intensity modulator is reflected in the injection-locked nanosecond pulse with an intense peak power of the megawatt class.
