Highly sensitive bending sensor based on Er3+-doped DBR fiber laser.
A short cavity Er(3+)-doped distributed-Bragg-reflector (DBR) fiber laser with a low polarization beat frequency has been demonstrated for bending measurement. The polarization beat frequency of the DBR laser is extremely sensitive to bending and can measure curvature changes as small as 1.8 x 10(-2) m(-1). Excellent agreement between experimental and theoretical results was obtained for bendin...
متن کاملA Unidirectional Er3+-Doped Fiber Ring Laser without Isolator
An Er"+-doped fiber ring laser with unidirectional operation without optical isolator has been investigated for different cavity conditions. The fiber ring laser cavity is built in such a way that the optical fields propagating in the two directions suffer different losses. As a consequence, the laser oscillation appears in a quasi-unidirectional form. By incorporating a fiber pigtailed bandpas...
متن کاملEr3+-doped fiber ring laser for gyroscope application.
Fiber-laser sensors have potential advantages over conventional fiber-optic interferometric sensors owing to their simplicity in both optical configuration and electronic signal processing." A fiber ring laser is a good candidate for rotation-rate sensing because of the same advantages, and such a fiber-ring-laser gyroscope was demonstrated by use of Brillouin gain in the fiber.4'5 The Brilloui...
متن کاملTm3+-doped CW fiber laser based on a highly GeO2-doped dispersion-shifted fiber.
A novel all-fiber laser based on a highly GeO2-doped dispersion-shifted Tm-codoped fiber, pumped at 1.56 µm wavelength and lasing at 1.862 µm wavelength with a slope efficiency up to 37% was demonstrated. The single-mode Tm-doped fiber with the 55GeO2-45SiO2 core was fabricated for the first time by MCVD technique. The laser produces spectral side bands, resulting from the four-wave mixing owin...
متن کاملPolarimetric DBR fiber laser sensor for strain-temperature discrimination
A polarimetric Distributed Bragg Reflector (DBR) laser sensor in a low birefringent Er-doped fiber has been proposed. The spectral overlap of two uniform fiber Bragg gratings (FBG) has been employed as filtering technique to achieve a Single Longitudinal Mode (SLM) regime. By measuring the RF beat frequency between the two orthogonal polarized lasing modes and the absolute wavelength of one mod...
