Abstract

A narrow-linewidth cw 5μm source based on difference frequency generation of a 1.3μm quantum dot external cavity diode laser and a cw Nd:YAG laser in periodically poled MgO:LiNbO3 has been developed and evaluated for spectroscopic applications. The source can be tuned to any frequency in the 5.095.13μm range with an output power up to 0.1mW, and in the 5.425.48μm range with sub-microwatt output. The output frequency is stabilized and its value determined by measuring the frequency of the two lasers with a remotely located frequency comb. A frequency instability of less than 4kHz for long integration times and a linewidth smaller than 700kHz were obtained.
