<start_of_turn>model
Low laser beam divergence, 1 to 0.1 mrad, has been exploited in optical alignment
techniques. Under this technique, usually highly directional visible He-Ne laser light
is used for obtaining fast, efficient and precise alignment of large structures like
construction of tunnels, bridges, positioning objects  and surveying.<end_of_turn><eos>
