Especially p-side up assembly leads to increasing thermal influence of neighboring emitters due to the low thermal conductivity of GaAs. Electro-magnetic fields inside and outside the laser-bar, for example caused by high frequency modulation (10 MHz) at a high current (up to 1 A), induce voltages into neighboring electrical circuits, hence the output power of neighboring emitters can be affected.enhigh-power diode laseraddressableprintingspatiallytemporally modulated intensity profile621conference paper
