Vertical-cavity surface-emitting laser for mid-infrared generation

The model of laser making use of GaAs/AlGaAs structure lattice nonlinearity for mid-infrared emission is proposed. Here, two-frequency near-infrared simultaneous oscillations are mixed in vertical-cavity surface-emitting device. The power of mid-infrared emission at wavelength about 10 /spl mu/m is shown to be 0.1-1 /spl mu/W in continuous wave operation.
