Abstract: In this paper, we report a high performance longwave infrared (LWIR, λ = 8-12 μm) quantum cascade laser (QCL) emitting at 9.0 μm. The effects of cavity dimensions on the performance of ...

Impact Statement: We investigated a high-power narrow-linewidth 976 nm broad-area semiconductor laser through external cavity feedback technology by employing a transmission grating as the dispersive ...

During the test, remote sensing images were sent from the satellite to the optical telescope on the truck. Wang Xingxingh, the company's technical director of laser communication said ...
