The coexistence of various spatial distributions of laser intensity in a multimode vertical-cavity surface-emitting laser (VCSEL) at fixed DC values was experimentally demonstrated. Their structures were characterized by different integrated intensities, polarization states, and sets of wavelengths. Spatial multistability was shown to lead to the appearance of multistability in the laser intensity and polarization multistability and was characterized by a strong local dependence of the laser intensity hysteresis behavior on the pump current. The effect of the diode-laser temperature on the manifestation of multistability was also investigated.

多模垂直腔激光器中多稳定性的实验研究

实验证明了在固定DC值下，多模垂直腔面发射激光器（VCSEL）中激光强度的各种空间分布并存。它们的结构以不同的积分强度，偏振态和波长组为特征。结果表明，空间多重稳定性会导致激光强度和偏振多重稳定性出现多重稳定性，其特征是激光强度滞后行为对泵浦电流的强烈局部依赖性。还研究了二极管激光温度对多重稳定性表现的影响。
