Abstract
A dispersive laser pulse stretcher and compressor comprises a stretcher portion and a compressor portion. A first mirror, a second mirror, a third mirror, a first grating, a first lens, and a first vertical retroreflector block comprise the stretcher portion. A fourth mirror, a second grating, a horizontal retroreflector, and a second vertical retroreflector block preferably comprise the compressor portion. The input beams for the stretcher and compressor are preferably parallel beams. The present invention also positions the first grating of the stretcher in a parallel plane with the second grating of the compressor. The present invention also includes a method for simultaneously aligning the input angles of the stretcher and compressor, the method comprises the steps of: removing the first and second diffraction gratings; aligning the input beam for the stretcher portion; aligning the input beam for the compressor portion; mounting the first and second gratings on a mounting block in parallel planes, and rotating the mounting block until the proper input angle for the laser wavelength is reached.
