Abstract: | The performances of stable- and unstable-resonator TEA CO2 lasers with cw injection are experimentally compared. Two types of measurements are reported. First, locking band-widths are measured for a wide range of cw injected powers. It is shown that 5- s 1-J single longitudinal mode pulses can be obtained with unstable resonator lasers for injected powers as low as 200 nW. Second, heterodyne measurements of the intrapulse TEA laser frequency are presented. The use of unstable resonators is experimentally proven to be the most efficient way to achieve reproducible high-power chirpless single-mode pulses at 10 m.This work has been supported by Direction des Recherches et Etudes Techniques |
