Abstract

We report on multi-wavelength arrays of master-oscillator power-amplifier quantum cascade lasers operating at wavelengths between 9.2 and 9.8 μm. All elements of the high-performance array feature longitudinal (spectral) as well as transverse single-mode emission at peak powers between 2.7 and 10 W at room temperature. The performance of two arrays that are based on different seed-section designs is thoroughly studied and compared. High output power and excellent beam quality render the arrays highly suitable for stand-off spectroscopy applications.

摘要

我们报道了工作波长在9.2至9.8μm之间的主振荡功率放大器量子级联激光器的多波长阵列。该高性能阵列的所有元件在室温下均具有纵向（光谱）以及横向单模发射，峰值功率在2.7至10W之间。对基于不同种子段设计的两个阵列的性能进行了深入研究和比较。高输出功率和优异的光束质量使这些阵列非常适合用于远距离光谱应用。
