中红外带间级联激光器的研究进展和市场发展前景OA

Mid-infrared band covers two important atmospheric windows and is also the absorption fingerprint area of numerous gas molecules,making it highly valuable in diverse applications,including gas detection,environmental monitoring,industrial control,medical diagnostics,infrared countermeasures,etc.Mid-infrared interband cascade lasers(ICLs)are a class of semiconductor lasers operating in the mid-infrared band.They have the advantages of low power consumption and high efficiency.They are suitable for various application scenarios such as portable gas detection,and have gradually become competitive mid-infrared light sources.Currently,the global ICLs market is predominantly controlled by foreign corporations,while the domestic ICLs industry is still in its early stage.Therefore,it is of great significance for China to promote the development of ICLs by clarifying the market application prospect,industrial development path and technology application direction.This paper outlines the major application scenarios of ICLs,reviews the development history of ICLs,and research progress of GaSb-based,InAs-based ICLs,and ICLs heterogeneous integration in recent years is reviewed in detail.On this basis,the market prospects and challenges are analyzed,and the development of ICLs in China is prospected.
