Implementation of a widely tunable microwave signal generator based on dual-polarization fiber grating laser.
In this paper, we demonstrate the implementation of a widely tunable microwave signal generator based on a dual-polarization fiber grating laser. The laser contains two strong, wavelength-matched Bragg gratings photoinscribed in an Er-doped fiber and emits two polarization modes when pumped with a 980 nm laser diode. By beating the two modes, a microwave signal with a signal-to-noise ratio over...
متن کاملExperimental Study of Fiber Laser Cavity Losses to Generate a Dual-Wavelength Laser Using a Sagnac Loop Mirror Based on High Birefringence Fiber
DWFL are considered profitable optical sources because of their advantages such as low cost, easy and affordable optical structures, low losses insertion and space optimization. Principal issue to generate two simultaneous laser lines resides in the cavity losses ad‐ justment. In DWFL designed with Erbium-doped fiber (EDF) as a gain medium there is a strong competition between the generated las...
متن کاملA widely tunable dual-wavelength CW Ti:sapphire laser with collinear output.
We report a collinear output and tunable dual-wavelength CW Ti:sapphire laser with a simple cavity configuration. The wavelength splitting range is easily tuned from 10 nm to 110 nm, which provides 56 THz bandwidth for terahertz generation. The total output power of two colors with the spatial mode of TEM(00) is between 700 mW and 300 mW, for small and large wavelength splittings, respectively,...
متن کاملAlternate Wavelength Switching in a Widely Tunable Dual-Wavelength Tm3þ-Doped Fiber Laser at 1900 nm
We demonstrate alternate wavelength switching in a widely tunable, dualwavelength Tm3þ-doped fiber laser operating at 1900 nm. A comb filter based on a Sagnac loop incorporating a length of high-birefringence fiber is used to define the lasing wavelengths. By simple variation of a polarization controller within the laser cavity, alternate and sequential switching between singleand dual-waveleng...
متن کاملAll-fiber dual wavelength passive Q-switched fiber laser using a dispersion-decreasing taper fiber in a nonlinear loop mirror.
This paper describes a proposal and successful demonstration of a dual wavelength all-fiber passively Q-switched erbium-doped fiber ring laser. The Q-switch operation was realized by using a nonlinear loop mirror that incorporated an unbalanced dispersion-decreasing taper fiber to act as a saturable absorber without additional elements. This setup enabled a fiber ring laser to achieve a perform...
