SUPERCONTINUUM GENERATION APPARATUS AND METHOD

摘要

Apparatuses and methods for supercontinuum generation using a laser beam and a plurality of condensed state transparent plates are presented. As an example, plate material to be used for one of the plurality of plates is determined. A thickness of the one of the plurality of plates is also determined. An allowable laser intensity of the laser beam is then determined to be »/(2n 0 n 2 L), where » is the central incident wavelength in vacuum, no is the linear refractive index, n 2 is the third-order nonlinear coefficient. A location of a next plate is then determined to be a distance downstream from the one of the plurality of plates where a laser intensity of the laser beam returns to a value of the determined allowable laser intensity.
