Abstract

This paper reviews the recent progress of the 0.6 micrometers wavelength range high power InGaAlP visible light lasers. A fundamental transverse mode cw oscillation was achieved over 40 mW for the transverse mode stabilized structure fabricated by metalorganic chemical vapor deposition. Stable operations over 5000 hours were attained under the condition of 10 mW output power and 40 degree(s)C ambient temperature. High power operation over 80 mW was achieved for a window structure InGaAlP laser which was made in a very unique and simple fabrication process using a bandgap energy change phenomena by the atomic ordering change of this material.
