论文摘要
我们介绍了一个简单的低成本外部空腔二极管激光器的设计，构造和仿真，其自由运行频率漂移速率为1.4（1）〜MHz/h，在852 nm处。通过紧凑，几乎单一的铝结构来实现这种性能，以最大程度地减少整个激光腔的温度梯度。我们提出了量化温度梯度影响的热有限元方法模拟，并表明漂移速率可能受到激光二极管衰老的限制。
We present the design, construction, and simulation of a simple, low-cost external cavity diode laser with a measured free-running frequency drift rate of 1.4(1)~MHz/h at 852 nm. This performance is achieved via a compact, nearly monolithic aluminum structure to minimize temperature gradients across the laser cavity. We present thermal finite element method simulations which quantify the effects of temperature gradients, and suggest that the drift rate is likely limited by laser-diode aging.
