Quantum cascade lasers (QCLs)

Quantum cascade lasers are semiconductor lasers that offer peak emission in the mid-IR range (4 μm to 10 μm). These devices are an excellent light source for mid-IR applications, such as molecular gas analysis and absorption spectroscopy. While DFB lasers achieve extremely narrow single-mode bands, our technology can also be customized for more tunable lasers. Hamamatsu’s quantum cascade lasers line lead the industry with meticulously manufactured performance at cost-effective prices.
