摘要：
An external-cavity semiconductor laser employing a grazing-incidence grating and 100-mu-m stripe gain-guided laser diodes is described. The laser oscillates in a single axial and spatial mode at currents below the free-running threshold of the diode. A maximum single-frequency power of 30 mW is obtained. The lasing wavelength is tunable over 300 angstrom. At higher drive currents, the output contains multiple axial and spatial modes, with a linewidth of 4 GHz. The maximum continuous output power is 230 mW.
