Abstract

The spectroscopic application of a new broadband microelectromechanical-system-tunable vertical cavity surface-emitting laser with single-mode coverage of 60 nm ( 245 cm 1 ) in a single, continuous sweep is described. The operation of the device is illustrated with high-resolution spectra of CO and CO 2 over 110 cm 1 ( 27 nm ) and 67 cm 1 ( 17 nm ) , respectively, with the CO band shown for high-pressure scans between 1 and 3 ba rs (0.1–0.3 MPa). The achieved tuning range opens up new opportunities for tunable diode laser absorption spectroscopy. The spectra were compared with HITRAN-derived model calculations. The benefits of a sensor based on this laser are greater speed, laser power, and tuning range.
