Abstract

A major improvement of a differential absorption lidar (DIAL) system for measurements of tropospheric water vapor and temperature is introduced. A Q-switched unidirectional alexandrite ring laser is injection seeded by a cw Ti:sapphire ring laser. Using an especially developed single-mode electronic, one starts the Q switch when the slave resonator is in resonance with the frequency of the Ti:sapphire laser. Long-term single-mode operation of the alexandrite laser is achieved. A single-shot spectral linewidth of <40 MHz and a frequency stability of 15 MHz rms can be specified. Thus what is to our knowledge the first single-mode DIAL system in the near infrared is presented.

Fig. 3

Measurement of linewidth and frequency stability of the single-mode laser. The upper figure shows a cross section of two orders of interference fringes averaged over 100 shots. The fringes were measured with a plane interferometer with a finesse of 30 and a plate separation of 12.5 cm, yielding a resolution of 40 MHz. Each shot showed single-mode operation. The linewidth of the 100-shot average is ≈43 MHz. An analysis of the frequency stability on a shot-to-shot basis is shown in the lower part of the figure. A rms frequency stability of 15 MHz is achieved.
