A novel laser system for rapid-wavelength scanning applications was developed. The wavelength-tuning mechanism is the soliton self-shift of femtosecond pulses in optical fiber. Increased coupling into the fiber causes an increased wavelength red-shift within the fiber. By varying the coupling efficiency, we can generate rapid wavelength scans. Here, we demonstrate tuning between 1.665 and 1.820 μm at 40 kHz repetition rate with 8 mW average output power. We applied this source to measure the overtone of the C–H stretch in gaseous butane.

Drawbacks, potential improvements of the system and possible applications in other fields are discussed.
