The integrated structures shown in Figures 1 and 2 may be employed to generate the second harmonic of GaAs/GaAlAs heterostructure lasers by nonlinear optical effects so that visible radiation in the 4000A to 4500A wavelength range may be produced, These lasers emit in the 7500A to 9000A wavelength range.
