Abstract: Abstract: Measured power–current curves of 660nm AlGaInP-based oxide-confined vertical-cavity surface-emitting lasers (VCSEL) are compared with calculated data by a cylindrical heat dissipation model to improve heat removal out of the device. Pulsed lasing operation of a 670nm VCSEL at high temperatures is demonstrated. At +120°C heat sink temperature we exceeded 0.5mW and at +160°C still output power were achieved.
