Abstract

Summary form only given. Here we describe the use of a non-critically phase-matched, temperature-tuned LBO crystal as an efficient material for second harmonic generation (SHG) of fundamental wavelengths of the LiF:F/sub 2//sup -/ laser, which has a 1030-1300-nm tuning range. The theoretical temperature-tuning curve for the LBO crystal, based on the data for refractive indexes and their dependence on the temperature given by Kato, is shown. As one can see, by changing the temperature of the LBO crystal, it is possible to maintain non-critical phase matching conditions for the whole tuning range of LiF:F/sub 2//sup -/ laser.
