Abstract
An improved high power spatial filter, system and method. In the system, an optical fiber is disposed inside a ferrule channel structure, and the channel structure is aligned with a focusing lens system. The end of the fiber is at a distance D from the channel opening that faces the focusing lens system, and D is determined by the system's numeric aperture factor and the cladding thickness of the optical fiber.
