Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. RakiÄ, Dragan Indjin +46
Quantum cascade lasers (QCLs) are unipolar semiconductor lasers first demonstrated in 1994. Since then, they have played a central role in advancing mid-infrared and terahertz phot…
Sub-doppler trace-gas photoacoustic spectroscopy
Jacopo Pelini, Stefano Dello Russo, Chenghong Zhang +10
Molecules are emerging as new benchmark for metrology and fundamental physics research, driving the demand for spectroscopic techniques combining high sensitivity and resolution. P…
Self-mixing-based photoacoustic sensing
Tecla Gabbrielli, Jacopo Pelini, Chenhong Zhang +7
Versatile, ultracompact, easy-to-handle, high-sensitivity sensors are compelling tools for in situ pivotal applications, such as medical diagnostics, security and safety assessment…
Shot-noise-limited emission from interband and quantum cascade lasers
Tecla Gabbrielli, Jacopo Pelini, Georg Marschick +12
The intensity noise of a laser source represents one of the key factors limiting the ultimate sensitivity in laser-based systems for sensing and telecommunication. For advanced app…
