Optical Time

A fiber-pumped single-frequency microchip erbium laser was developed and characterized with the aim of using it in coherent Optical Time Domain Reflectometry (OTDR) measurements and sensing. The laser is pumped by a fiber-coupled 976 nm laser diode and provides 8 mW TEM00 single frequency output power at 1.54 µm wavelength, suitable for efficient coupling to optical fibers. The amplitude and phase noise of this 200 THz oscillator were experimentally investigated and a Relative Intensity Noise (RIN) control loop was developed providing 27 dB RIN peak reduction at the relaxation oscillation frequency of 800 kHz

Frequency Radiation

Generation of single frequency radiation from a semiconductor laser based on a special laser module (amplifying laser module) is presented. The multi-mode emission with the spectral bandwidth of 100A$^{o}$ is converted to single mode one with a narrow bandwidth of 2A$^{o}$ in the presence of external optical feedback. Wavelength tunability of the laser emission over the range of 4-10 nm is also shown. The results could be used in high speed optical communication, WDM and other applications.
