Abstract

In order to get a dual-wavelength tunable CO2 laser, a two-resonator laser was developed, which consists of an output coupler and two diffraction gratings. The output pulse characteristics and tuning range were also analyzed experimentally. The experimental results indicate that the two resonators can oscillate independently. Two widely tunable laser pulses are generated without spatial competition. The temporal synchronization of the lines is controlled by rotating the gratings within a narrow range for varying their losses.
