Abstract

Lasers with a wavelength of 2μm are useful for applications that require eyesafe propagation through the atmosphere.^1,2 This Letter discusses a single frequency laser that could be used as an injection locking source for a high power oscillator, or as a local oscillator source for a coherent receiver. The monolithic design of this laser is especially appealing because of its compactness, ruggedness, stability, and simplicity.
