提出了一种基于20个压应变GaInP量子威尔斯阱的多量子阱结构的垂直外腔面发射激光器系统，工作波长约为665 nm，采用单片集成的分布式布拉格反射镜。在腔内金刚石散热器的帮助下，激光器以连续波模式工作。显示了TEM 00高斯光束轮廓和光束传播因子M2≤1.05的操作，以及激光线的高分辨率光谱，其显示了金刚石的标准具效应。激光器的最大输出功率超过1.2 W，斜率效率ηdiff= 18%。在最大输出功率下，激光谐振的波长为670 nm，这是迄今为止在超过1 W的功率下报道的最短波长。通过旋转双折射滤波器在一个扩展的折叠腔安排的波长调谐21 nm的实现。
We present a vertical external cavity surface-emitting laser system based on a multi-quantum-well structure with 20 compressively strained GaInP quantum wells for an operation wavelength of around 665 nm with a monolithic integrated distributed Bragg reflector. With the help of an intra-cavity diamond heatspreader the laser operates in continuous-wave mode. Operation with a TEM00 Gaussian beam profile and a beam propagation factor of M2≤1.05 is shown as well as a high resolution spectrum of the laser line, which shows the etalon effect of the diamond. The laser can be operated at a maximum output power exceeding 1.2 W with a slope efficiency of ηdiff=18%. At maximum output power the wavelength of the laser resonance is at 670 nm, which is shortest reported until now at powers exceeding 1 W. By rotating a birefringent filter in an extended folded cavity arrangement a wavelength tuning of 21 nm was attained.
