Amplitude Noise and Linewidth Reduction of an Ar+ Laser
No full textFrequency modulation spectroscopy is used to frequency stabilize an Ar+ laser at 515 nm with respect to a commercial passive cavity. Two transducers, a slow and a fast one, are used. The fast transducer is also used to perform amplitude
stabilization of a laser beam. Measured amplitude and frequency spectral noise densities are reported. A simplified scheme of
the circuitry used to reduce amplitude noise is shown. Noise characteristics of the realized system are adequate to perform spectroscopy of hyperfine-structure transitions of molecular iodine
