Abstract
A high-speed-scanning laser system is presented consisting of three elements in series: an erbium-fiber femtosecond laser emitting at 1.56 μm, a nonlinear fiber, and a dispersive fiber. The system produces chirped broadband pulses that scan from 1.67 to 1.44 μm at a rate of 0.6 nm/ns. The spectroscopic potential of the system is demonstrated by conducting sweeps in the ν1+ν3 band of C2H2 at a repetition rate of ∼2 MHz. A 3.5-GHz photoreceiver combined with a 20-Gsample/s oscilloscope is used to monitor the optical signal. Instrument broadening due to the time response of the detection system limits the spectral resolution of the system to 0.4 cm-1, which, however, is sufficient to resolve individual rotational absorption features of C2H2.
