Mode-locked fiber laser gyroscope
Optics Letters, 1993We describe a new form of an all-fiber-optic gyroscope that utilizes a fiber laser. The Sagnac interferometer is used as a loop reflector with a modulated reflectivity to produce actively mode-locked optical pulses. The rotation-induced phase shift is obtained from the timing shift of the pulses.

Self-mode-locked Cr:forsterite laser
Optics Letters, 1993We have demonstrated self-sustaining operation of a mode-locked chromium-doped forsterite laser in which short-pulse formation is entirely due to the nonlinearity of the laser crystal. Stable pulse trains are generated for intracavity pulse energies from 35 to 120 nJ. Pulses less than 100 fs in duration are obtained over the range of 1.23–1.28 μm, with
