Multi-wavelength Brillouin-Raman fiber laser utilizing enhanced nonlinear amplifying loop mirror design.
We demonstrate a single-spacing, multi-wavelength Brillouin-Raman fiber laser utilizing an enhanced cavity of nonlinear amplifying loop mirror. In this structure, the optimization of multi-wavelength lasing is done with proper adjustments of coupling ratio and Brillouin pump power. When setting the Raman pump power to 300 mW, up to 28 channels with an average 17 dB optical signal-to-noise ratio...
متن کاملWavelength-tunable, passively mode-locked fiber laser based on graphene and chirped fiber Bragg grating.
We demonstrate a wavelength-tunable, passively mode-locked erbium-doped fiber laser based on graphene and chirped fiber Bragg grating. The saturable absorber used to enable passive mode-locking in the fiber laser is a section of microfiber covered by graphene film, which allows light-graphene interaction via the evanescent field of the microfiber. The wavelength of the laser can be continuously...
متن کاملDevelopment of Fiber Bragg Grating Sensor System Using Wavelength-swept Fiber Laser
Fiber Bragg grating (FBG) sensors based on the wavelength division multiplexing technology are ideally suited for structural health monitoring. In many applications, it is desirable to form several arrays of optical fiber sensors to monitor the response of structures. In the present study, we constructed an improved FBG sensor system using a wavelength-swept fiber laser which exhibits high outp...

A simple, cost-effective and switchable five-wavelength fiber ring laser based on a chirped moiré fiber grating (CMFG) and a wavelengthtunable Sagnac loop interferometer (FSI) filter is proposed and experimentally demonstrated. To serve as wavelength selective element, the CMFG possesses excellent comb-like filtering characteristics, and its fabrication method is easy and flexible. The usage of...
متن کاملMulti-modes Fiber Ring Laser Sensor Combining One Fiber Bragg Grating Reflector
A multi-longitudinal-mode fiber ring laser sensor is firstly proposed and experimentally demonstrated. Beat frequencies between any two longitudinal modes are used as sensing signal. The core component of the system is a multi-longitudinal-mode fiber ring cavity laser sensor based on beat frequency demodulation method. The theory of beat signal generation and strain measurement are discussed in...
