摘要:

1632 nm激光器在三波混频过程中通过频率转换将铷基量子存储器的波长(795 nm)与电信波段(通常为1550 nm)连接起来方面具有非常重要的应用。介绍了一种基于泵浦增强差频产生的1632 nm激光源。它具有300 mW的输出功率,与模拟一致,量子效率为55%。一个平均功率波动0.51%,超过一个小时,观察到,200 kHz的线宽,使用延迟自外差法测量。

英文摘要:

A 1632-nm laser has highly important applications in interfacing the wavelength of rubidium-based quantum memories (795 nm) and the telecom band (typically 1550 nm) by frequency conversion in three-wave mixing processes. A 1632-nm laser source based on pump-enhanced difference frequency generation is demonstrated. It has 300 mW of output power, in agreement with simulations, and a 55% quantum efficiency. An average power fluctuation of 0.51% over one hour was observed, and 200-kHz linewidth was measured using a delayed self-heterodyne method.
