Compact 100 mW fiber laser with 2 kHz linewidth

A novel single frequency fiber laser with more than 100 mW output is presented. Low noise and a coherence length of >75 km make this laser extremely useful in sensing, LIDAR, and coherent communication applications. @2003 Optical Society of America OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (140.3570) Lao;ers. single-mode; (140.5680) Rare earth and transition metal solid-st...

High energy, single-mode, narrow-linewidth fiber laser source using stimulated Brillouin scattering beam cleanup.

We propose an original nonlinear beam cleaning fiber laser architecture to obtain high energy pulses with a good beam quality and a narrow linewidth. The output beam of a large core Er:Yb co-doped multimode fiber amplifier (M(2) approximately 6, 220 microJ) is converted into a near diffraction limited beam (M(2) = 1.6) through a stimulated Brillouin scattering injection seeded beam cleanup proc...

Zhen We report a novel design of photonic crystal fiber (PCF) with a rectangular array of four closely-spaced, highly elliptical air holes in the core region and a circular-air-hole cladding. The proposed PCF is able to support ultra-wideband sing...

Sub-100 fs pulses from an all-polarization maintaining Yb-fiber oscillator with an anomalous dispersion higher-order-mode fiber.

We present an Yb-fiber oscillator with an all-polarization-maintaining cavity with a higher-order-mode fiber for dispersion compensation. The polarization maintaining higher order mode fiber introduces not only negative second order dispersion but also negative third order dispersion in the cavity, in contrast to dispersion compensation schemes used in previous demonstrations of all-polarizatio...
