Abstract :
Multi-mode cw blue-violet diode-lasers exhibit interference revival when the interferometric path-length-difference is much greater than the self-coherence time. Using the equally-spaced and recurring interference envelopes, high-resolution mode-spacing measurement is possible without using high-resolution spectrometers.
