Abstract

A photodissociation iodine laser with an intracavity spatio-temporal light modulator controlled by an external photodetector array is studied experimentally. The feasibility of lasing in different directions determined by a light signal is demonstrated. The laser radiation energy is 11 J per pulse, and the duration and divergence of the pulse are 180 μs and 1.2 × 10−4 rad, respectively.
