Laser noise in fiber-optic interferometer systems
The amplitude stability of single-mode channeled-substrate planar diode lasers has been measured as a function of frequency (100 Hz–1 MHz) and driving current. The relative noise spectrum showed a decrease with increasing frequency and an overall reduction at all frequencies as the output power of t...

| Zusammenfassung: | The amplitude stability of single-mode channeled-substrate planar diode lasers has been measured as a function of frequency (100 Hz–1 MHz) and driving current. The relative noise spectrum showed a decrease with increasing frequency and an overall reduction at all frequencies as the output power of the laser was increased. These results are compared with similar measurements of the most stable commercial single-mode HeNe lasers. The problems of laser amplitude noise in fiber-optic sensor systems is briefly discussed. |
