Abstract
An illumination system including at least one laser source, at least one anisotropic light expanding element and a wavelength conversion element is provided. The at least one laser source emits a laser beam. The at least one anisotropic light expanding element is disposed on the transmission path of the laser beam and causes the laser beam to expand along a light expanding direction. The light expanding direction is substantially parallel to the slow axis of the laser beam. The wavelength conversion element is disposed on the transmission path of the laser beam. A projection apparatus is also provided.
