We present high power, high reliability, single mode ridge waveguide laser diodes operated in an external cavity configuration. The cavity is formed by installing an InGaAsP/InP laser chip into a cavity with a Bragg grating mirror (BGM). The laser has fiber optical output. The devices are characterized by narrow spectral width operation, in pulsed and CW modes. We obtained 1.7 W output power in single mode fiber at 2 - 10 ns pulses, at a 1550 nm wavelength, with an optical line width of 0.15 nm. For CW excitation, the devices emitted 200 mW optical power with a bandwidth of less than 0.01 nm. These devices exhibit high temperature stability of the laser line spectral position. The construction of these devices enables cost-efficient, narrow bandwidth lasers in the wavelength range from 1300 to 1900 nm.
