| A Broadband Pulsed External-Cavity Quantum Cascade Laser Operating near 6.9μm | |
| 摘 要： | We report an external cavity quantum cascade laser(EC-QCL) operating near 6.9 μm using the Littman-Metcalf configuration.The EC-QCL works in a pulsed mode and can be tuned continuously from 1340 to 1640 cm~(-1)by only tilting the tuning mirror.The fine tuning ability of the EC-QCL is demonstrated by measuring the absorption spectrum of water in the ambient air with a lock-in amplifier. |
