An ophthalmic surgical apparatus is disclosed comprising a main laser generator for emitting an operating laser beam of infrared energy and an auxiliary laser generator for emitting a marker laser beam of visible light. The laser beams are superposed before reaching an operating system by a plurality of mirrors and a laser beam expander for each of the laser beams. The laser beam expanders have separate entrance lenses and a common exit lens. Preferably, the operating optical system comprises a focusing lens which doubles as the common exit lens of the laser beam expander.
