We report a laser-driven fiber-optic gyroscope (FOG) with an angle random walk of 0.9 mdeg/√h, an Allan-deviation minimum of 4.9 mdeg/h, and an Allan-deviation maximum (or true drift) of 12.6 mde…
A model of laser cooling in a fiber with a doped cladding shows that a radiation-balanced fiber laser (RBFL) made of silica can produce substantial output powers. Bidirectional pumping is found to …
Phase noise can be modulated onto the output of a laser with an electro-optic phase modulator (EOM) to create a highly incoherent broadened source with low intensity noise. This technique leaves a …
We report a new fiber sensor utilizing a spring-loaded circular diaphragm to detect extremely weak acoustic waves. When exposed to an acoustic wave, the diaphragm vibrates parallel to itself relati…
We present a new model of backscattering drift in a fiber-optic gyroscope (FOG) using square-wave modulation and demodulation and interrogated with light of arbitrary lineshape and linewidth. By mo…
