At high temperatures the threshold current of GaxIn1−xAsyP1−y stripe lasers shows a more marked decrease with pressure than at room temperature. The temperature sensitivity term T0 increases from about 65 K at atmospheric pressure to about 115 K at 7 kbar. The results can be best interpreted in terms of intervalence band absorption.
