A single-frequency 1.5 um microchip erbium laser, diode-pumped through optical fiber, was developed and characterized with the aim of using it in coherent OTDR sensing applications. The laser is pumped by a fiber-coupled 976 nm laser diode and 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...
