Mode-locked fiber laser gyroscope.
We propose and demonstrate a novel fiber-optic gyroscope in the form of a mode-locked laser consisting of a laser cavity formed by a planar mirror at one end, a gain medium, and a Sagnac interferometer at the other end. The Sagnac interferometer serves as a reflector as well as a rotation-sensing element. The output of the gyroscope is a series of short optical pulses. The separation of two set...
متن کاملUltrafast Optics with a Mode-locked Erbium Fiber Laser
We describe an ultrafast optics advanced laboratory comprising a mode-locked erbium fiber laser, auto-correlation measurements, and a free-space parallel grating dispersion compensation apparatus. The simple design of the stretched pulse laser used nonlinear polarization rotation mode-locking to produce pulses as narrow as 108 fs, full-width at half-maximum, at a repetition rate of 55 MHz and a...
متن کاملActively mode-locked Raman fiber laser.
Active mode-locking of Raman fiber laser is experimentally investigated for the first time. An all fiber connected and polarization maintaining loop cavity of ~500 m long is pumped by a linearly polarized 1120 nm Yb fiber laser and modulated by an acousto-optic modulator. Stable 2 ns width pulse train at 1178 nm is obtained with modulator opening time of > 50 ns. At higher power, pulses become ...
متن کاملWS2 mode-locked ultrafast fiber laser
Graphene-like two dimensional materials, such as WS2 and MoS2, are highly anisotropic layered compounds that have attracted growing interest from basic research to practical applications. Similar with MoS2, few-layer WS2 has remarkable physical properties. Here, we demonstrate for the first time that WS2 nanosheets exhibit ultrafast nonlinear saturable absorption property and high optical damag...
متن کاملHigh-sensitivity mode-locked fiber laser gyroscope.
We report significant performance improvement of a mode-locked fiber laser gyroscope. A Fabry-Perot cavity GaAlAs laser diode whose front facet was antireflection coated was used as a gain medium. The rms noise equivalent rotation rate measured with a time-interval counter was improved to 0.06deg/ radicalh. The long-term drift of the gyroscope signal was reduced to 100deg/ radicalh after a pola...
