具有温度稳定发射波长的915 nm量子点激光器已被实现用于非制冷高功率应用。优化网点几何结构的大面积激光器的热致波长漂移为0.09 nm/K，比量子阱激光器的热致波长漂移低3.5倍。尽管有了这一改进，激光器在连续波工作时仍显示出超过3W的高输出功率和55%的壁塞效率。
915 nm quantum dot lasers with temperature stable emission wavelengths have been realised for uncooled high-power applications. Broad area lasers with optimised dot geometry exhibit a thermal induced wavelength shift of 0.09 nm/K, which is 3.5 times lower than for quantum well lasers. Despite this improvement the lasers show high output powers of more than 3 W and wallplug efficiencies of 55% in continuous-wave operation.
