Abstract

We report the use of frequency-modulation spectroscopy with a Nd:YAG-pumped dye laser of 5-nsec pulse duration. In spite of the fact that the dye laser is not transform limited and has 30% peak-to-peak intensity fluctuations, we are easily able to measure absorptions as small as 2%.

Power spectrum of the frequency-modulated dye laser recorded with a 10-GHz FSR spectrum analyzer. The upper and lower side bands are clearly resolved with νm = 1963 MHz. The apparent splitting at ν = 10 GHz reflects the strong fluctuations of our dye laser.
