This work describes the development of a single-frequency 1.5-μm microlaser, diode-pumped by a fiber-coupled 976 nm laser diode. The laser is designed for coherent OTDR measurements used to perform remote diagnostic of gas and oil pipelines. The new microlaser provides some 10 mW single-frequency output power at 1533.5 nm wavelength, suitable for sensing and measurements with optical fibers. Amplitude and phase noise are under investigation for specific use OTDR remote sensing in the range of a few tens of kilometers.
