Femtosecond neodymium-doped fiber laser operating in the 894-909-nm spectral range Abstract: We demonstrate a practical ultrafast Nd-doped fiber laser operating in the 894-909-nm spectral range. Using ...

An optical dual sensor for oxygen and temperature is presented that is highly oxygen sensitive and covers a broad temperature range. Dual sensing is based on luminescence lifetime measurements. The ...

Abstract: A novel fiber Bragg grating (FBG) sensor configuration using three broadband light sources of different wavelength bands for the interrogation of FBG sensors distributed over 75 km of fiber ...
