We fabricated and characterized a membrane external-cavity surface-emitting laser (MECSEL) emitting at 1640 nm. This is the first, to the best of our knowledge, description of this type of laser emitting at the long-wavelength telecommunication band. Double-sided diamond heat spreaders were used to efficiently dissipate heat. Emission producing 1.2 W of power was demonstrated. We suggest that optimization of the laser has the potential to increase generated power.

膜外腔表面发射激光器，发射波长为1640 nm

我们制造并表征了在1640 nm处发射的膜外腔表面发射激光器（MECSEL）。就我们所知，这是对长波长电信频段发射的这种类型的激光的首次描述。双面金刚石散热器用于有效地散热。演示了产生1.2 W功率的发射。我们建议优化激光有可能增加产生的功率。
