In certain embodiments, an ophthalmic laser system for treating a floater in a vitreous of an eye includes a laser device that directs laser pulses towards the floater to yield cavitation bubbles that create a bubble jet to treat the floater. In some examples, the laser device includes a beam multiplexer that splits a laser beam into multiple beams that form the cavitation bubbles that create the bubble jet. In some examples, the laser device directs laser pulses towards the floater according to a pulse pattern that forms the cavitation bubbles that create the bubble jet.
