MW-QDL is a new exploration pathway into novel compact, multiplex quantum dot-based laser sources. The investigation is focused on visionary aeronautics and space exploration. This is a potentially enabling technology for missions seeking compact, multiple wavelength quantum-dot based laser sources. The Decadal Survey recommends missions, such as GACM, to measure atmospheric constituents, but has stated that there is presently no suitable laser for GACM. An anticipated benefit of this project is to invent the specialized lasers that may be useful for future missions. MW-QDL will cover a wide operating range (UV-vis to MIR). This technology could enable compact, light weight, multiplex lasing capability for commercial space exploration.
