摘要

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.
