Abstract
An example architecture for providing a delay line for optical techniques. The delay line architecture includes a focusing element that has a focal axis disposed parallel to its length. The line of symmetry provided by the focal axis obviates path-length-dependent aberrations caused by the off-axis beam translations. The systems also provide varying geometries of movable mirrors, including a galvanometer mirror and a rotating polygonal mirror. The systems and methods also provide techniques for generating and detecting coherent Raman spectra using a picosecond probe pulse.
