A slave pulsed laser stabilizes the frequency by using the master laser frequency to stabilize a cavity in the slave pulsed laser. The slave pulsed laser includes an optical modulator, a cavity, a cavity modifier, and an output generator. The cavity includes an end reflector, a laser generator, an optical injector, and an output coupler. The optical modulator receives a continuous wave laser signal that includes a carrier frequency. The optical modulator then modulates the continuous wave laser signal to generate two sidebands around the carrier frequency. The laser generator generates a first laser signal in the cavity. The optical injector then injects the continuous wave laser signal with the first laser signal. The output generator generates an output signal based on the continuous wave laser signal. The cavity modifier then modifies a length of the cavity based on the output signal wherein the cavity is in resonance with the frequency of the continuous wave laser signal. The output coupler then transmits the pulsed first laser signal from the output coupler. The slave pulsed laser advantageously transmits the pulsed laser signal with non-detectable chirp for high signal-to-noise ratio.
