宽带室温连续/脉冲量子级联激光器 Multimode lasers operating in pulsed.CW mode on TE cooler with gain bandwidth ranging from 200 to 350 cm-1. Available from 780 cm-1 to 1660 cm-1 Description Broad gain Fabry-Pérot devices are devices especially designed to operate as gain media for External Cavity (EC) systems. These devices can also be used to provide illumination over a large spectral range with a relatively even spectral density.
