Stable room temperature operation of planar green laser diodes at 512nm was achieved on ZnSe substrates, which are conductive in the first 200μm from the top due to post-growth aluminium doping. The threshold current density is 900-1000A/cm2 and the operating voltage is ∼14V. The lifetime in pulsed operation exceeds 1 h.
