Abstract

Tunable laser spectroscopy measurements on low-pressure gases have been performed using magnetic-field-tuned lead-salt semiconductor diode lasers in the 4- to 7-μm region. Use of magnetic field tuning in conjunction with the conventional current tuning is shown to significantly increase the versatility of diode lasers in high-resolution spectroscopy. Details of the tuning characteristics for fields up to 90 kG are presented.
