Abstract
A dichroic beam splitter module is disclosed for separating a main pulse laser beam from a pre-pulse laser beam each traversing a common beam path. In one embodiment, two dichroic elements are physically aligned along the beam path and are configured to pass the pre-pulse, a laser light having a first wavelength, to target material located near an irradiation site yet reflect the main pulse, a laser light having a second wavelength. The reflected main pulse is then further reflected by two reflective elements or mirrors from the first dichroic element to the second dichroic element and then on to the irradiation site. In alternative embodiments, the first mirror is deformable to alter beam characteristics of the reflected main pulse beam and the second mirror is adjustable to align the main pulse beam to the irradiation site.
