Measured power-current curves of 660 nm 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 670 nm VCSEL at high temperatures is demonstrated. At +120 degrees C heat sink temperature we exceeded 0.5 mW and at +160 degrees C still 25 mu W output power were achieved.
