Security device with compact mid-ir laser

摘要: A compact mid-IR laser device utilizes a quantum cascade to provide frequencies suitable for use in molecular detection by signature absorption spectra. The nature of the is obtained owing an efficient heat transfer structure, small diameter aspheric lens and monolithic assembly structure hold optical elements fixed position relative one another. housing size may be approximately 20 cm×20 cm or less. Efficient achieved using thermoelectric cooler TEC combined with high thermal conductivity spreader onto which thermally coupled. not only serves dissipate conduct same TEC, but also as platform secure within relationship on have 10 mm less positioned provided collimated beam output from laser. hermetically sealed rugged, light weight portable MIR source.
