Abstract

Un formador de haz para transformar un haz MM con el perfil plano de distribución de intensidad incluye un bloque de extremo que es fundido en un extremo corriente abajo de una fibra que da salida al haz MM a lo largo de una trayectoria dentro de una cabeza de láser. El formador de haz tiene además un colimador montado en la cabeza de láser corriente abajo del bloque de extremo. El haz colimado MM entonces es enfocado en la zona de trabajo con una cintura de haz caracterizada por un perfil de intensidad gaussiana. La región gaussiana puede proporcionarse en la proximidad de la cintura de haz mediante el posicionamiento del colimador, de modo que la región gaussiana del haz plano MM sea ubicada dentro del bloque de extremo y en el plano focal del colimador. De manera alternativa, la región gaussiana puede proporcionarse dentro de la cintura al utilizar un elemento óptico difractivo que transforma el perfil plano de distribución en un perfil de forma de dona.
