A 532 nm second-harmonic beam from a diode-pumped Nd:YAG laser is first passed through a spatial filter to produce a clean, expanded profile, and then collimated by a 4 inch, 65 cm focal-length lens to uniformly illuminate the SLS. The diffraction patterns at different propagation distances are captured using a lensless Nikon D100 camera.
