Abstract:
An investigation was made of fluctuations of the output frequency of a pulsed diode laser emitting at ≈ 10 μ. An analysis of signals transmitted by a Fabry–Perot interferometer made it possible to determine the frequency dispersion Δ νl ≈2.5 MHz for a normal distribution law and also the correlation time of frequency fluctuations, which was 0.2 μsec.
