A Zn diffusion stripe laser is fabricated by the metalorganic chemical vapour deposition and the open-tube, two-step, solid-phase diffusion technique. The threshold current is 9.4 mA and the lasing wavelength is 780 nm at 20 degrees C. The laser operates in the fundamental transverse mode and the astigmatic distance is less than 1 mu m. The laser has operated for over 1000 h at 60 degrees C with a power of 3 mW.
