Abstract

Long range water vapor DIAL-systems require efficient and rugged laser sources. The quasi-three-level transition from R₁ to Z₅ in Nd:GSAG with 943nm wavelength is a promising candidate. An actively Q-switched Nd:GSAG laser was established. Up to 31mJ output pulse energy and up to 26Hz repetition rate was achieved. Injection seeding was used to obtain single frequency operation. The seed laser is a distributed feedback laser diode. Laser frequency was stabilized by ramp-hold-fire method. By tuning the wavelength of the seed laser a 0.83nm tuning range of the pulsed Nd:GSAG laser was obtained. Measured by Fabry-Perot interferometer the spectral line width was approximately 50MHz.
