Semi-automated manufacturing process for cost-efficient resonantly tunable quantum cascade mid-IR-range laser modules

https://www.eurekalert.org/news-releases/1085460

"complex/ expensive fabrication overcome using cost-efficient semi-automated micro-opto-electro-mechanical system grating scanner in an external optical cavity... high brilliance/ spectral tunability enables FTIR spectroscopy inline measurements... industry-ready, couples modules with complementary spectral ranges, economies of scale, pick-and-place instead of assembly by hand... combines multiple laser sources into multi-core... spectral measurement >1 million wavenumbers/ second... many spectroscopy applications"
