Optical device with phase-locked diodelaser array
摘要:
An optical device includes a phase-locked diodelaser array (10), a collimator lens (17), and behind the collimator lens a prism system (30, 34) of at least one prism to broaden the far field radiation pattern in the lateral plane (XY) and a spatial filter (19) to select a favored mode. The laser radiation is concentrated into a single, round and diffraction limited spot (V).
