我们利用不同光栅槽密度的光栅实现了4-7μm光谱范围内的窄带可调谐红外辐射。我们实现了低至22 nm的带宽采用衍射光栅具有500线/mm的槽密度在5.6μm。
We demonstrate a narrow-band-width tunable infrared radiation in the spectral range 4–7μm with gratings having different groove densities. We achieve a band width as low as 22 nm employing a diffraction grating having a groove density of 500 lines/mm at 5.6μm.
