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 of the 200 THz oscillator are under study for its use in specially designed OTDR measurements for remote sensing.
