Abstract
Second-harmonic generation of surface-emitted blue Light has been achi eved in (In,Ga)As/GaAs quantum well edge-emitting lasers. The blue lig ht is generated by the nonlinear interaction of the internal fundament al fields of a continuously pumped laser. These lasers exhibit room te mperature threshold current densities as low as 200 A/cm(2) and produc e about 2.6 nW of blue light for 9.8 mW of fundamental power. The peak emission of the blue light is at 487 nn and the spectral spread is ab out 1.7 nm. (C) 1996 American Institute of Physics.
