The far-field pattern and its intensity profile during laser oscillation (Fig. 3 (c), (d)) show that the oscillation was achieved with an extremely narrow beam divergence angle (of as low as 0.05°), ...

Knowledge of a laser beam's shape and output-power distribution is critical for optimizing laser performance. Neil Savage summarizes the latest beam-profiling products on the market. People using ...

A large 55 mm aperture is insensitive to beam size or angle of divergence, which means greater ... Designed for high power laser manufacturers and industrial applications such as cutting, the ...
