Room temperature, continuous wave operation of independently addressable, dual spot, single spatial mode GaInP laser diodes emitting at 675nm is reported. Threshold currents of 30mA and singlemode output powers exceeding 30mW per emitter have been obtained. Crosstalk between emitters is as low as 0.3% with a 50μm centre to centre spacing.
