An investigation was made of the spectral composition of the radiation emitted from a cw stripe AlGaAs--GaAs injection heterolaser operating at room temperature in an external dispersive resonator. Narrow-band (..delta..lambda< or =0.15 nm) stimulated emission with an output power up to 20 mW was obtained. The output radiation was tunable in a range of approx.10 nm centered on the wavelength of 884 nm and in this case the maximum cw single-frequency power was 4 mW. Excitation of several longitudinal external-resonator modes (within the limits of the narrow emission band) was accompanied by rf intensity fluctuations consisting of mode beats (250--500 MHz) and a noise band at much lower frequencies (30--100 MHz).
